针对地面目标(主要是坦克)的“发射后不管”武器系统,需要一种具有自动目标识别能力(ATR)的高性能的寻的器。寻的器主要任务是:能在全天候和战场条件下从地杂波中识别目标。要满足这样苛刻的要求,方法之一就是把两种互补的探测器结合成一个双模寻的器。94GHz雷达探测器和无源红外成象IR探测器(8到10μm)的结合就是一种很有希望的实例。本文叙述了由这样2种探测器组成的双模寻的器。该寻的器包括双模前端,属于各探测器的专用处理器,双模处理器和用于前端控制的数据处理器。除了这些工作分部件外,还包括一些实验性的装置。为了确保数据合成的成功,双模寻的器被做成一个共用孔径系统,对准同一视场,具有相同的帧速。其设计一量度包括时间调整和简化空间定位。为确保空间定位,雷达探测器做成单脉冲系统,把各探测器在同一角空间中的探测物体联系起来。在截获飞行试验中,数据合成的原理和基础是每个探测器预先分类的被探测体数据,而定位则取决于被探测的物体。截获飞行的结果表明,这种双模寻的器的性能明显地高于任一单一探测器做成的系统。
A “fired after” weapon system for ground targets (mainly tanks) requires a high-performance finder with automatic target recognition capability (ATR). The main task of the finder is to identify the target from clutter in all weather and battlefield conditions. To meet such a demanding requirement, one of the methods is to combine the two complementary detectors into a dual-mode seeker. The combination of a 94 GHz radar detector and a passive infrared imaging IR detector (8 to 10 μm) is a promising example. This article describes a dual-mode seeker made up of two such detectors. The finder includes a dual-mode front end, a dedicated processor for each detector, a dual-mode processor, and a data processor for front-end control. In addition to these sub-components of work, but also some experimental devices. In order to ensure the success of the data synthesis, dual mode finder was made into a common aperture system, aligned to the same field of view, with the same frame rate. Its design metrics include time adjustments and simplified space positioning. In order to ensure spatial positioning, the radar detector is made as a single pulse system that connects the detectors in the same angular space. In intercepted flight tests, the principle and basis of data synthesis are the pre-classified detector data for each detector, and the positioning depends on the object being probed. The results of the intercepted flight show that the performance of this dual mode seeker is significantly higher than that of any single detector.
