| 摘 要： | 为克服传统的线性调频连续波(LFMCW)雷达在多目标分辨中的局限性,分析了LFMCW雷达差拍信号频谱特点,提出了一种基于二次混频和"CLEAN"技术的新方法,解决了多目标分辨中虚假目标问题.计算机仿真结果显示当检测信噪比在-10dB以下时仍能正确识别各个目标,表明了算法的有效性.

| Abstract: | In order to overcome the limitation of multitarget resolution for linear frequency-modulated continues wave (LFMCW) radar, a novel method is presented based on twice mixing and "CLEAN" technique by analyzing the beat signal spectrum in this paper. The method may figure out the problem of pseudo target in multitarget resolution and its effectiveness is proved by the computer simulation that the multitargets can be identified correctly as the detection SNR below -10dB. |
