摘要
本文就HF Radar中数字直读法产生LFM电路出发,分析了LFM寄生调相产生的原因,以及对系统检测性能的影响,最后给出了计算机的仿真结果。
The article analyses the conditions under which spurious phase modulation of Linear Frequency Modulation (LFM) is produced and studies its effect on the system detection performance based upon the LFM circuit of digital direct-read algorithm. And finally it presents the computer simulation results.
