限制接收机带宽是雷达系统中提高信噪比(SNR)的常用方法,相应的也会引起输出波形的失真。本文主要分析了多相码数字脉压雷达系统中,接收机有限带宽对脉压输出结果所造成的影响。运用五点滑动窗平均法在计算机上进行了模拟,并给出了仿真结果。
Limiting the receiver bandwidth is a common method of increasing the signal-to-noise ratio (SNR) in radar systems and correspondingly can also cause distortions in the output waveform. This paper mainly analyzes the influence of the receiver’s limited bandwidth on the pulse pressure output in multi-phase digital pulse pressure radar system. The five-point sliding window averaging method was used to simulate the computer and the simulation results were given.
