摘要:

针对高烈度空地对抗环境下,制导雷达引导高超声速拦截武器打击来袭目标的迫切需求,开展针对高超声速合作目标的快速截获与跟踪技术研究,从雷达体制、波形设计、跟踪模型3方面着手,解决高超声速导弹/炮弹雷达散射截面积(radar cross section,RCS)小不易截获,飞行速度快且速度分布范围广难以检测跟踪等问题。通过基于窄带信号和脉冲多普勒(pulse Doppler,PD)处理的雷达工作体制设计,降低距离单元走动的影响,提升强杂波背景下弱小目标的检测能力;通过基于双脉组参差的制导波形设计,提升可利用的多普勒空间,实现目标的广速度域检测;通过基于先验信息引导的截获屏搜索与基于速度域判决的航迹起始与航点关联模型构建,实现对高超声速合作目标的快速截获与稳定跟踪,并在半实物仿真实验中对模型的有效性进行了充分验证。

Abstract:

Aiming at the urgent requirements of guidance radar to guide hypersonic weapons to intercept incoming targets in fiercely air-to-ground military confrontation, rapid acquisition and tracking technologies are studied. There are several problems need to be solved: one is the RCS of hypersonic missiles/shells is small that not easy to acquire, the second is the hypersonic missiles/shells flight speed is high and has a wide speed distribution that difficult to detect and track. The problems are solved from three aspects: radar system design, waveform design and tracking model design. Through the design of radar operating system based on narrowband signal processing and PD processing, the influence of range migration is reduced, and the detectability of dim target under strong clutter background is improved. Through the design of guidance waveform based on double PRF(pulse repetition frequency) sets, the velocity ambiguity in Doppler is resolved. Through the design of search interception screen based on prior information and the design of taking velocity into track initiation and track correlation model, the rapid acquisition and stable tracking of hypersonic cooperative targets are realized. The effectiveness of the proposed model is fully verified in the semi-physical simulation test.

Key words: radar, hypersonic cooperative target, pulse Doppler processing, multiple pulse repetition frequency (PRF) sets, fastly acquiring, tracking
