Super - resolution spatial spectrum estimation is applied in this dissertation to realize bearing resolution by utilizing the different bearings between targets and first - order sea echoes . the simulation of radar echoes in one resolution cell is presented based on the theoretically analyzing hf sea clutter sea clutter reflection characteristic and sea echo spectrum stretching mechanics 本文從分析高頻海雜波反射特性以及平臺運(yùn)動引起海浪展寬機(jī)理入手,建立便于理論研究的一階展寬的海雜波和二階海雜波模型;在分辨單元上對雷達(dá)回波信號進(jìn)行了仿真。
