摘要

在有源干扰和杂波存在的情况下，采用频率捷变和运动目标检测相结合的系统，提高了目标的检测能力。在兼容的MTD系统中，由于使用了FA，给MTD处理器带来了短序列相干处理、抑制地杂波、非相干综合检测以及在不同FA模式下的正常工作等新问题。适当的措施包括:滤波器模式的选择、滤波器设计的优化、卡尔曼滤波的应用、一种新的CFAR电路以及三种检测算法。所有这些都应用于DMTS(数字运动目标选择器)处理器的设计，该处理器是实验兼容雷达系统的一个单元。

The processor of MTD and CFAR in compatible system of FA and MTD

A compatible system of FA (frequency agility) and MTD (moving target detection) has improved target detectability while both active interference and clutter exist. Owing to using the FA, some new problems are created for the MTD processor in a compatible system: coherent processing with short sequence, ground clutter rejection, non-coherent integrated detection, and proper operation in the different FA modes. The appropriate measures introduced include the selection of FA modes, the optimization of filter design, the utilization of Kalman filtering, a new CFAR circuit, and three algorithms for detection. All these are applied to the design of a DMTS (digital moving target selector) processor which is a unit of an experimental compatible radar system.<>
