摘要
讨论了机载脉冲多普勒雷达对主杂波（ＭＬＣ）频率补偿信号源的技术要求及基本实现方法，阐述了直接数字式频率合成（ＤＤＳ）的基本原理和频谱性能，给出了ＤＤＳ产生主杂波补偿信号源提高杂波跟踪性能的方案，并通过实验验证了其可行性。
This paper discusses the specifications of MLC compensation signal and its basic realizations for Airborne Doppler Radar. The theories of DDS are stated and its spectral performance is analyzed. Then a MLC compensation signal source consisting of DDS to improve the MLC-tracking performance is given and its feasibility is verified by experiment.
