摘要
脉冲多谱勒技术因能使雷达在极为恶劣的地物、海浪和强杂波背景中有效的发现目标,广泛应用于机载火控雷达,而在信号处理中其核心问题为解距离模糊和速度模糊,经典的方法之一为中国余数定理,在此方法的基础上对解距离模糊采用二次门限的方法提高了发现概率,采用重频步进法减少了频率错误概率并且提高了运行速度。
Pulse doppler technology is in widely used of airbone fire control Radar,because it can effectually detect target in ground oceanic and violent clutter environment.However the most important problem in signal process is Range and velocity ambiguity resolution, The classical method is Chinese remainder theorem,based on this theorem, use secondary threshold to improve the probability of discover,use frequency step reduce the probability of error frequency and accelerate the programe implement.
