The video quality of electro-optical guidance systems in visible spectrum (0.4-0.7μm) is degraded by hazy atmospheric conditions to such an extent that the contrast and tracking range are considerably reduced by even very light haze. The objective of this paper is to show that with practical modifications to a conventional electro-optical system, it is possible to obtain a substantial improvement in system performance. The main measures for this are to replace the existing vidicon with a silicon target tube...

The video quality of electro-optical guidance systems in visible spectrum (0.4-0.7μm) is degraded by hazy atmospheric conditions to such an extent that the contrast and tracking range are considerably reduced by even very light haze. The objective of this paper is to show that with practical modifications to a conventional electro-optical system, it is possible to obtain a substantial improvement in system performance. The main measures for this are to replace the existing vidicon with a silicon target tube for increased response in the near infrared region, to replace the standard optics with a continuous zoom lens for improved initial target acquisition and discrimination, etc.

由可见光制导系统(0.4~0.7μm)改进为可见-近红外制导系统(0.4~1.1μm)可以获得明显改善效果,信息量增加,图象清晰度与对比度皆提高。作用距离达到原来系统的2~3倍。如原通过系统观察到海上目标船为10km,现提高到约25km等,在有薄雾的大气条件下,经过改进的光电系统可以使性能得到明显的提高。 改进的具体措施包括:(1)用硅靶管或具有同一波段的CCD摄像器件代替硫化锑管而增加近红外灵敏度。(2)正确选择大气背景与目标特征频谱段。(3)采用视频处理技术提高对比度。(4)提高近距初制导对目标截获功能和远摄识别效果即选用半自动或自动连续变焦系统取代定焦系统。(5)图像处理技术,用软件与硬件方法对面目标及点目标分别采取对策。以及对目标的多特征提取技术等。

Discriminating the potential targets is an important step in detection of the infrared search and track (IRST) systems.By learning of the acquisition criterion of IR targets,the paper has put forward a decision tree discriminant method and a fuzzy integrated assessment method.It is also critical in the studies of the combined use of two methods.The work has given a convincing basis and instrumentality for the discrimination of IR ordinary targets and small long distance targets.

Two key problems,angle measurement and angle prediction, of the swift target acquisition in array radar are studied. Firstly, from the respect of required beam arrangement, discrimination feature and the performance of angle measurement, the two algorithms named amplitude comparison monopulse like algorithm and average weighted with amplitude algorithm, for measuring the targets angle with array radars are studied. The method for nonlinear adjustment when the average weighted with amplitude algorithm is applied is posed. Then, the algorithms for predicting the targets angle with tracking filters are analysed. A simple decoupled filter named SDF is presented. At last, these algorithms are tested in a simulation system for array radar.
