Research on Aerial Target Trajectory Measurement Method Based on LFMCW Radar Ranging

针对舰空导弹命中精度考核难的问题,采用双差拍-傅立叶变换处理原理,提出了一种应用多基站线性调频连续波(LFMCW)雷达对舰空导弹和靶标进行实时测量定位,进而确定导弹和靶标空中遭遇轨迹的方法。给出LFMCW雷达测距原理,重点对测量过程中可能产生的测量误差进行分析,并通过仿真验证可行性。

Aiming at the problem of difficulty in assessing the hitting accuracy of ship-to-air missiles,a method of real-time measurement and positioning of ship-to-air missiles and targets by using multi-station linear frequency-modulated continuous wave(LFMCW)radar is proposed based on the principle of double-beat FFT,and then the encounter trajectory of missiles and targets is determined.The principle of LFMCW radar ranging is given,and the possible measurement errors occuring in the measurement process are focused on and analyzed,and the feasibility is verified by the simulation.
