伪码连续波交会对接雷达信号处理机设计

介绍了某伪码连续波交会对接雷达信号处理机设计.在测距中,提出用噪声较小的载波相位△伪距测量值对伪距进行处理,得到高精度测距值.在测角中,提出了一种干涉仪天线阵结构和干涉仪解模糊算法,针对通道载波相位误差可能引起的解模糊错误,又提出了一种纠正方法,仿真显示,在发生解模糊错误的概率高达0.42的情况下,该方法仍然可以识别并纠正所有解模糊错误.实验表明,该信号处理机可以满足空间航天器交会对接的要求.

Pseudo-code CW RVD Radar Signal Processor Design

In this paper,a design of pseudo-code CW Rendezvous and Docking(RVD) radar signal processor is presented.In ranging procedure,the pseudo-range is processed with delta pseudo-range from the carrier loop with small noise,and the precision is improved.In angle measuring,an antenna configuration and interferometer ambiguity-resolving algorithm are proposed,and to eliminate the error caused by carrier phase error,a correction method is introduced,through which all ambiguity-resolving error can be recognized and be corrected even when the error probability is up to 0.42.Tests indicate that the signal processor can meet the requirements of Rendezvous and Docking.
