摘　　要：针对弱小目标空间坐标测量系统中的目标检测与识别,提出了一系列提高系统捕获率的方法.该方法根据图像与目标特性,采用改善背景图像质量、判别目标成像特性和设置成像时间窗口来获得目标识别和交汇数据,最后对识别交汇结果进行反演来提高系统弱小目标检测识别能力从而最终获得较高捕获率.试验表明这些方法对于提高系统捕获率是有效的.To the dim and small target detection and recognition of the coordinate measurement system, some methods were presented to increase the system acquirement rate. Based on the images and target characteristics, by improving the quality of background image, distinguishing target imaging characteristics and setting time window, recognition and intersection data was got. A higher acquirement rate of the system was obtained by counter-computing these data to increase the ability of the dim and small target detection and recognition. These methods had been applied into the accomplished system design and test and had been proved to be effective to increase the acquirement rate of the system.
