从虚假反射背景中识别来自一个感兴趣目标的雷达反射信号的问题可以看成是一个空间和时间上的模式识别问题。每个扫描区间预计的假模式检测数和碰到一次模糊的概率可以用每次扫描的假观测点数、传感器测量维数、传感器分辨单元、监视空域和每维上的最大可容许目标速度的函数表示。由一个短时基反向时空相关器后接一个较长时基的正向递归时空相关器组成的级联过程具有双重优点,它对模糊不很敏感,且比较简单。
The problem of identifying a radar reflection signal from a target of interest from a false reflection background can be viewed as a spatial and temporal pattern recognition problem. The number of false pattern detections and the probability of encountering once ambiguity for each scan interval can be calculated as a function of the number of false observations per scan, the number of sensor measurements, the number of sensor resolution cells, the surveillance airspace, and the maximum allowable target velocity in each dimension Said. The cascade process consisting of a short-time inverse space-time correlator followed by a longer time-base forward recursive spatio-temporal correlator has the double advantage that it is not sensitive to blur and is relatively simple.
