低截获概率雷达低截获概率雷达low intercept probability radardiiiehuo gQil位leida低截获概率雷达(low intereept prob汕11-ity radar)探测信号难以被敌方雷达对抗侦察设备和反辐射导弹导引头截获与识别的雷达。它综合采用包括功率域、频率域、时间域和空间域等多方面降低截获概率的多种技术来实现低截获概率。功率域低截获概率技术主要是降低雷达发射机的峰值功率并保持其平均功率。通常采用加宽脉冲宽度、扩展信号频谱等脉冲压缩技术，这是降低雷达截获概率的基本措施。频率域低截获概率技术主要是超宽带雷达技术，使雷达的信号带宽大于雷达对抗侦察设备的瞬时信号带宽，使其只能收到雷达信号的部分频率成分，难以查明雷达的全部技术参数，从而降低截获概率。时间域低截获概率技术主要包括频率捷变、脉冲宽度与重复频率捷变和脉内调制波形捷变等技术。利用雷达波形在时间域内的快速变化，使雷达对抗侦察设备在短时间内难以查明雷达的全部参数，以降低其截获概率。空间域低截获概率技术主要有降低天线的副瓣电平，采用多基地雷达技术和稀布阵天线技术等。雷达对抗侦察设备能截获多基地雷达的发射信号，并测定其发射机的方位，但不能测定接收机的方位，从而难以实施电子干扰。稀布阵综合脉冲孔径雷达将雷达的大功率发射机分解成很多小功率发射机，并分散配置在不同地点，利用数字波束形成技术，将各发射机分散辐射的小功率在空间又合成为具有一定指向的大辐射功率。这种技术既保证了雷达的探测距离，又降低了被雷达对抗侦察设备截获的概率。低截获概率雷达是在雷达对抗斗争中发展起来的。20世纪80年代初期，美国、英国、荷兰等国研制出低截获性能较好的试验性雷达。90年代初期，美国B一2隐身轰炸机上装备的AN/APQ一181雷达问世，标志着低截获概率雷达技术又有了新的发展。低截获概率雷达的发展趋势是:解决降低截获概率和提高雷达探测性能之间的技术兼容性问题;发展低截获概率火控雷达和进一步研究新体制低截获概率雷达等。(重天爵)
