【摘要】：针对信息时代电子战背景下雷达抗干扰性能评估测试设备多、组织实施难的难题,提出一种基于指标计算模型和半实物仿真系统的测试方法。分析了烧穿距离和有效干扰扇区等关键指标同雷达性能参数的内在联系。为满足抗干扰测试小型化、综合化、智能化的发展需求,提出了一种新型的雷达对抗综合信号生成系统设计方案。该系统利用先进DSP处理技术、接口电路设计和终端显控技术,实现了状态数据采集、目标回波模拟以及复杂对抗场景灵活设置;结合某型雷达开展了抗干扰性能测试,通过烧穿距离、距离波门拖引试验验证了测试系统的合理性和有效性。研究成果为实现复杂战场环境下的雷达性能测试和抗干扰策略制定提供了重要支撑。
[Abstract]:In the context of electronic warfare in the information age, radar anti-jamming performance evaluation and testing equipment is more difficult to organize and implement. This paper presents a testing method based on index calculation model and hardware-in-the-loop simulation system. The internal relations between the key indexes such as firing distance and effective jamming sector and radar performance parameters are analyzed. In this paper, a new design scheme of radar countermeasure integrated signal generation system is put forward, which uses advanced DSP processing technology, interface circuit design and terminal display control technology to realize state data acquisition. The target echo simulation and the complex countermeasure scene are set up flexibly, and the anti-jamming performance test is carried out in combination with a certain type of radar. The range gate towing test verifies the rationality and effectiveness of the test system. The research results provide an important support for radar performance testing and anti-jamming strategy formulation in complex battlefield environment.
