我们推导了一个简单的解析表达式，说明了在积分样品的相位中，由于白高斯误差或噪声引起的相干加权积分增益的变化。仿真结果表明，对于任何合理的相位噪声标准偏差值，我们的表达式都是非常准确的。该结果对于估计振荡器噪声、残余运动补偿误差以及主要表现为相位误差的其他系统缺陷对相干信号处理系统的性能影响是有用的。
We develop a simple analytic expression for the change in coherent weighted integration gain due to a white Gaussian error or noise in the phase of the integrated samples. Our expression is shown by simulation to be very accurate for any reasonable value of phase noise standard deviation. The result is useful in estimating the performance impact on coherent signal processing systems of oscillator noise, residual motion compensation errors, and other system imperfections that are manifested primarily as phase errors.
