摘要
舰载雷达的MTI、MTD系统必须补偿由于载体运动而产生的多普勒频率的影响。本文分析了用数字方法进行舰速补偿,并作了实验,结果表明:这种补偿对舰速、舷角、仰角、雷达工作频率、重复频率代码等的量化精度都提出了严格要求。
In ship-borne radar, the effect of doppler frequency shift caused by platform moving must be compensated for MTI and MTD processing. This paper gives the analysis of a digital compensation method. The experimental results indicate that there are strict requirements for quantization accuracies of ship speed, nose angle, elevation angle, radar operating frequency and PRF,in performing this compensation.
