摘要
伪随机二相编码连续波(PRC-CW)雷达应用于多目标环境下时,如果各个目标回波功率相差较大,弱目标回波信号会淹没在强目标回波信号的距离旁瓣中,对信号检测造成很大的影响。针对上述问题,提出采用基于CLEAN思想的逐次消去脉压-FFT处理方法消除强目标回波信号的距离旁瓣对弱目标回波信号的影响。理论推导和仿真实验证明了该方法的有效性。
When pseudo random code continuous wave (PRC-CW) radar is applied in multi-target circumstances,the weaker echo signal will be drowned in the range sidelobe of the stronger echo signal, which has a great negative effect on target detection. In this paper, a new method using pulse compression-FFT based on CI.EAN technique is proposed to improve the detection performance of the radar system, which can effectively suppress the interference of close-in targets and range sidelobes of the stronger signals. The theoretical formula and simulation indicate the method is effective and feasible.
