摘要: 本文討論了步進(jìn)頻率信號(hào)的設(shè)計(jì)問(wèn)題,針對(duì)順序步進(jìn)頻率信號(hào)有速度一距離耦合的缺點(diǎn),提出了隨機(jī)序列步進(jìn)頻率信號(hào)形式及其多組頻率捷變相參處理方法,該信號(hào)形式具有較好的速度、距離分辨能力和雜波抑制能力。

Abstract: The designing of step frequency signal is concerned.Stochastic sequence step frequency signal is advanced to overcome the ordered step frequency signal s default of range-velocity coupling. The advanced signal is better than the ordered step frequency in clutter rejection and range-velocity resolution. -
