在信噪比较低时，还可以用滑动互相关算法进一步提高处理增益。
The skip cross-correlation can improve the processing gain further more when the SNR is lower.
由于LPI雷达具有大时间带宽积，故超宽带雷达具有高处理增益而抵消侦察接收机在侦察距离上的优势。
Because of the LPI radar's large time-bandwidth product, UWB radar has a high processing gain to cancel the advantage of the intelligence receiver at intercept range.
