They are the property of sum and difference beams, the errors of the elements and channels and different pulse repeating frequency ( PRF).
这些因素包括和差波束的特性、阵元和通道的误差、不同的脉冲重复频率（PRF）。
For the sake of reducing the multi-path error when radar is tracking low altitude target, a new method was developed which can keep the low side-lobe level of both sum and difference beam in single pulse angulation is satisfied with Taylor/ Bayliss distributions based on array antenna.
为降低雷达跟踪低空目标中时的多径误差，采用了基于阵列天线的、用Taylor和Bayliss分布来满足单脉冲测角中的和、差波束都具有低副瓣电平的方法。
To sum up, there are some original and innovative points as follows: 1. Analyze the influence of random phase error on pulse compressing of LFM and put forward a SVD and rotation of Ambiguity Function to remove the noise or better the compressing effect.
分析了随机相位误差对宽带线性调频信号方位向匹配压缩的影响，并提出通过奇异值分解分离信号和噪声空间的方法达到改善脉冲压缩效果，降低噪声影响的目的。
