中文摘要：
火控雷达正常工作时需要对目标进行持续照射,其信号极易被敌方侦察系统所截获.针对这一问题,提出一种可以提高现役火控雷达低截获性能的辐射控制策略.该策略将间歇开机与雷达组网相结合,实时计算出火控雷达对目标的跟踪精度,在满足跟踪任务需求的门限精度时,转换到重频低的雷达工作,不满足则立即转换到重频高的雷达工作.结果表明,在该辐射控制策略下,火控雷达网不仅能保持对目标的有效跟踪,其低截获性能也获得了提高.
英文摘要：
Fire-control radar need continually illuminate the target, whose signal is liable to be intercepted by the enemy reconnaissance system. Aiming at the problem, a radiation control strategy was proposed to improve the LPI （low probability of intercept） performance of active service fire-control radars. In the control strategy, intermittent working radars were combined into a network, and the tracking accuracy was computed in real time. If the tracking accuracy met the required threshold, the radar with lower PRF （pulse repetition frequency） would be switched on, or the radar with higher PRF would be immediately switched on. The results showed that, in the radiation control strategy, fire-control radars network not only could keep tracking the target, but also had an increased LPI performance.
