硬戈壁沙漠杂波研究

THE CLUTTER RESEARCH OF HARD GOBI DESERT

对新疆库尔勒地区硬戈壁沙漠地杂波进行了研究．得到了Ｃ波段低擦地角（０．１°－７°）下有色杂波值，其值范围为－６０－－２０ｄＢ；并进行了白化处理，得到相应此有色杂波的白色杂波值，其值为一常数－２５ｄＢ，其电压幅度为±０．８Ｖ，不随擦地角变化．

In this paper, We have studied the clutter of hard Gobi desert by C-Band Radar in Xinjing Province.We have obtained colour clutter curve varied with depression angle (0. 1°- 7°). The values are range: -60--20 dB. also colour clutter has been whitened to whitened to white clutter i. e., white noise, the value is a constant -25 dB, not varied with depression angle.
