Method for Recognizing Intrapulse Modulation Types of Radar Signals

This paper addresses the identification of various types of intra-pulse signal modulation. First, we introduce the feature differences between various radar signals. Based on the data of the signal to be tested, we identify the modulation type using methods such as Short-Time Fourier Transform (STFT), digital instantaneous frequency measurement, and feature histogram. We provide the corresponding calculation process for key parameters. By combining the principled design of MATLAB and the construction of the SYSTEM GENERATOR model, we propose a new method for intrapulse identification. The effectiveness and accuracy of the proposed method are validated by comparing simulation data with model data.
