一、引言信号处理的目的,在于通过对输入信号加以处理,消除各种噪声和由噪声引起的不稳定性,以易于析取信息,并提高该信息的质量。在现代,雷达的用途极为广泛,遍及各个方面,有空中交通管制用的警戒雷达,FCS/跟踪雷达,气象观测雷达和高分辨力合成孔径雷达。雷达分为民用和防卫之用,可设置在地面,搭载在舰船、飞机以及导弹上。应输出的信息内容根据雷达的这些用途而各不相同,而且对噪声范围及其信号质量的影
I. INTRODUCTION The purpose of signal processing lies in that the input signal is processed to eliminate all kinds of noise and instability caused by noise so as to easily extract information and improve the quality of the information. In modern times, the use of radar is extremely extensive and covered in various aspects with alert radar for air traffic control, FCS / tracking radar, meteorological observation radar and high resolution synthetic aperture radar. Radar is divided into civilian and defense purposes, can be set on the ground, equipped with ships, aircraft and missiles. The information content to be output varies according to these uses of the radar, but also affects the noise range and its signal quality
