摘要
该文将大时宽带宽积的空间相位编码步进频率(PCSF)信号与m序列码相结合,应用于多发单收体制下的分布式小卫星雷达系统,获得很好的距离和多普勒分辨率。仿真结果验证了该信号模型的可行性。
In this paper, the combination of the phase coded stepped frequency and the m-sequences is applied to the distributed space-based radar system using the mode of multi-emitter and single-receiver, and the system achieves excellent range resolution and Doppler resolution. The simulation and performance analysis demonstrate the feasibility of this signal model.
