Abstract In recent years, low-cost modified suicide drones and drone swarm tactics have rapidly spread globally. Traditional air defense and anti-missile systems are difficult to achieve equivalent defense of "fighting low cost with low cost" due to high costs, strict precision requirements, and insufficient scene adaptability. Aiming at this pain point, this paper proposes a hierarchical low-cost dual-band acoustic countermeasure system, which mainly consists of two types of acoustic countermeasure equipment: one is a mobile dual-band acoustic countermeasure unit, including two forms of disposable acoustic anti-missile missiles and recyclable acoustic countermeasure platforms, focusing on long-distance swarm interception; the other is a fixed directional convergent acoustic defense device, focusing on close-range normalized defense of important buildings. The two types of equipment integrate ultrasonic and infrasound cooperative jamming technology. The mobile unit innovatively adopts a capsule-shaped acoustic coverage mode with an intelligent multi-mode trigger mechanism, and the fixed device adopts a directional beam convergent design with higher precision and stronger power. The two work together to form a complete dynamic defense system. Research shows that the system relies on the integration of mature civilian components. The mobile unit does not require high-precision guidance, and effectively deals with dense drone swarms through area-type killing. The single-use cost of a single disposable unit can be controlled within 220 US dollars, and the single sorties cost of the recyclable version drops to less than 15 US dollars after recycling; the fixed device can be on duty 24 hours a day to accurately intercept penetrating suicide drones, with an overall countermeasure success rate of over 92%. It can effectively solve the problems of saturation attacks and single-point raids by low-cost drones, filling the technical gap in the current low-cost anti-drone field. This paper also clarifies the system architecture, technical principles of each equipment, parameter selection and scene adaptation scheme, providing practical support for the implementation of defensive anti-drone technology. Update 1 Do you really think this paper is merely a technology-oriented application paper? (Beijing Time: 22:32, March 8, 2026) This paper is based on three underlying ideological frameworks proposed by the author (myself) in early research: Trait Locking Science (penetrating superficial features to reach the essence directly), Prediction-Regulation Dual-Drive Game Theory (Positive Game) and Reverse Game, and CEC (Convergent-Explosive Communication) Theory. The core theoretical kernels across multiple dimensions are uniformly projected onto engineering application scenarios. Although I do not directly cite the previous theoretical achievements, the core ideas run through the entire paper, forming a self-consistent cross-domain methodology implementation. The purpose of writing this paper is actually quite simple: an inspiration struck, and I wanted to challenge what the whole world currently deems impossible. As I already stated in The Three Rigid Laws of Artificial Intelligence (doi:10.5281/zenodo.18901760) , for me, nothing is impossible—there are only things I am not interested in and areas I have not yet set foot in. After all, my ZUST Theory (doi:10.5281/zenodo.18769528) extends upward to cosmology, and my TFR Theory (doi:10.5281/zenodo.18738297) downward to the field of food flavor. Up to now, there is nothing I cannot accomplish. On the contrary, my theoretical system has subverted or filled numerous gaps in academic circles. This paper is precisely to tell academia and the world that cracking drone swarm tactics is extremely simple for me, because it only requires existing technologies and no new theories need to be created to achieve a decisive victory over drone swarm tactics. The dual-band acoustic near-field resonance system for countering drone swarms in this paper, though an independent application chapter with no explicit citation of previous theoretical results, is designed throughout with the core ideas of penetrating superficial features, reaching the essence directly, dynamic game, chain gain, and global restraint. It is a typical achievement of the extension of the underlying academic system to real-world engineering. My Prediction-Regulation Dual-Drive Game Theory (Positive Game) and Reverse Game previously achieved a 100% winning rate and infinite penetration in the paper on human-machine game, which was ultimately elevated to the essential definition of life and tools, and further sublimated into The Three Rigid Laws of Artificial Intelligence—a sublimation derived from three core conditions after achieving certain victory in games. It will be almost impossible for the future AI field to break through my three rigid laws. My CEC (Convergent-Explosive Communication) Theory possesses the most robust justification structure available to humanity today: the other-proof and self-proof structure. The objective dissemination data of Paper A (Certain Victory in Human-Machine Games) is open and unalterable; the objective dissemination data of Paper B (CEC Theory) is equally open and unalterable. Paper A serves as external proof for Paper B, and Paper B forms self-proof for itself, creating a closed and dynamically enhanced loop that cannot be overthrown—this is the most robust justification structure in existence. Trait Locking Theory is the foundation of my research and the key that allows me to navigate freely across various fields. Taking this paper as an example: I have circumvented the core disadvantage of acoustic waves—propagation attenuation—by designing the sound source itself as an anti-missile/drone platform to make the sound source actively approach the target, or adopting a fixed, directionally focused high-power design for building defense. At the same time, I have strengthened its inherent advantages: The superposition of dual frequencies (ultrasound + infrasound) achieves synergistic enhancement of damage, and existing targets have no possibility of defending against both types of acoustic waves simultaneously; Area-type killing, upgrading the traditional spherical killing radius to a capsule shape to precisely counter drone swarm tactics; Two mobile modes (disposable and recyclable) plus fixed directionally focused defense devices form a three-layer superimposed dynamic defense system. The following are my three ideological systems: (For my other papers, you can click on the author's name under the title to enter the author's paper page) 1. The Idea of Prediction-Regulation Dual-Drive Game Theory (Positive Game) and Reverse Game — Hidden in the Offensive and Defensive Structure (Positive Game Theory (doi:10.5281/zenodo.18338725) the fixed directionally focused acoustic device features high power and high precision, specially designed for the defense of important buildings. As the final piece of the puzzle of the system, it achieves dead-angle-free defense. When my scheme outperforms drone swarms in both cost and efficiency, how can the opponent break through? If they choose to defend, their costs will soar; if they choose not to defend, their swarm tactics will be completely neutralized. This is the unsolvable nature of my dual-band acoustic scheme for countering drone swarms. The only real game here is the battlefield cost game—and this will be an insurmountable chasm for the opponent.(P
