扫描敏感系统中信号处理主要决定于二种要求:信号探测/峰值提取和多帧相关。本文略述和比较了目标脉冲探测技术和它们峰值的提取技术。文中讨论的脉冲技术包括匹配滤波器,最小二乘滤波器,部分波滤波器,非线性滤波器和图样识别技术。同时也讨论了在不能分辨的脉冲中提取峰值的问题。讨论的多帧相关技术包含二维窗口,多维窗口,多项式跟踪,矢量相关和矩量匹配技术, Signal processing in scanning sensitive systems is mainly determined by two requirements: signal detection / peak extraction and multi-frame correlation. This article outlines and compares target pulse detection techniques and their peak extraction techniques. The pulse techniques discussed in this article include matched filters, least squares filters, partial wave filters, nonlinear filters and pattern recognition techniques. The problem of extracting peaks in indecipherable pulses is also discussed. The multi-frame correlation techniques discussed include two-dimensional windows, multi-dimensional windows, polynomial tracking, vector correlation and moment matching techniques,
