摘要
目前, 制导**系统导引性能评估主要采用室内仿真和实弹射击方法。但是, 受模拟条件的限制, 室内仿真存在目标瞬变作用机理描述不足及过程复现可信度低等难题; 而外场实弹射击则存在试验样本量有限, 目标环境设定单一且射击条件无法保证一致性的问题, 难以全面考核出**系统对环境和干扰的适应性。针对这一问题, 提出了一种介于室内仿真与外场实弹试验之间的中间验证考核方法, 在接近真实复杂战场环境条件下, 构建了制导**系统的可视化动态测试平台, 获取导引头探测、识别和跟踪目标过程的同步、实时可视化观瞄图像, 提取目标信息并实现导引性能评估。这种方法在靶场环境下针对实际靶标目标进行静态、动态跟踪试验, 能够为激光、毫米波、电视以及红外等不同制导模式的导引头系统进行集成试验与测试, 可为室内仿真提供目标背景的直接驱动数据, 提升仿真逼真度;同时, 也可多次重复考核导引环节的关键能力, 弥补实弹射击试验数量的不足, 为**系统研制过程提供了一种全新的测试验证手段。
Abstract
Presently, indoor simulation and live ammunition firing are the main methods to evaluate the guidance performance of guided weapon system. However, due to the limitation of simulation conditions, there are some problems in indoor simulation such as inadequate description of target transient mechanism and low reliability of process reproduction. For live ammunition firing, the limited sample size, single environment settings and inconsistency of firing conditions limit the application. And this make it difficult to comprehensively assess the environment adaptability of weapon system. In order to solve this problem, an intermediate verification and assessment method was proposed for the real complex battlefield environment. In this work, a visual dynamic test platform for the guidance weapon system was constructed to obtain synchronization and real-time visualization of the seeker detection, recognition and tracking targets. The target information was extracted and the guidance performance was evaluated. Using this method,static and dynamic tracking tests could be carried out for actual target in shooting range environment. It can conduct integrated tests for seeker systems with different guidance modes such as laser, millimetre wave, television and infrared. It can provide direct data of targets and backgrounds for indoor simulation to improve simulation fidelity. It can also repeatedly check the key ability of guidance link and make up the insufficiency of firing test quantity of live ammunition. This would provide a new test and verification for weapon system development.
