Abstract Aircraft phased array radar systems using planar arrays have larger detection areas and higher target detection efficiency, but also require larger real-time computational resources and more complex resource scheduling algorithms to support them. In this paper, based on the multi core Digital Signal Proces-sor (DSP) signal processing hardware platform, the target identification, de-tection, ranging and angular measurement of the radar signal after pulse-pressure, as well as based on multi-frequency waveforms to complete the airspace search for far, medium and near range targets, target interception and tracking. In this manuscript, the multi-core deployment of moving targets detection (MTD) algorithm is realized by using Fast Fourier Transformation (FFT) filter scheme, and the acceleration ratio of 8. 22 times is obtained com-pared with that of single-core. The multi core deployment of the Constant False Alarm Rate (CFAR) algorithm is achieved using three different strate-gies, namely, the Greatest of CFAR algorithm (GO\CFAR), the Smallest of CFAR algorithm (SO\CFAR), and the Mean Level CFAR algorithm, and achieves a speedup ratio of 19. 61 times as compared to that of a single core. Finally, the internal and exter nal field tests are conducted, and excellent re-sults of the internal and external flight following test verification are ob-tained. The experiments show that the proposed design has better azimuth and pitch angle accuracy compared with others.
