MT信号处理使独立的输入噪声信号相关。因此,当MTI脉冲积累时,降低了检测性能。使用模拟技术,对输出是非高斯分布的小数目和中数目的样本,进行了噪声积累损失计算。结果表明:2、3、4和5脉冲的MTI积累损失各自近似为;1.0、1.8、2.2、2.5分贝。
MT signal processing correlates independent input noise signals. Therefore, when MTI pulses accumulate, the detection performance is reduced. Using simulation techniques, noise accumulation loss calculations were performed on small and medium non-Gaussian samples. The results show that the MTI accumulation losses of 2, 3, 4 and 5 pulses are approximately 1.0, 1.8, 2.2 and 2.5 dB respectively.
