摘　　要：借鉴传统雷达截获因子的概念,首先推导了成像雷达截获因子的表达式,并研究了临界发射功率和隐蔽成像距离。然后,建立了雷达隐蔽成像可采取的技术措施。最后,通过仿真分析验证了不同技术措施的隐蔽成像性能。仿真结果表明,在雷达采用30 MHz带宽的信号时,针对灵敏度为-65 dBm的侦察接收机,可在169.9 km距离处实现隐蔽成像。Referring to the concept of traditional radar interception factor,the expression of imaging radar interception factor is firstly derived. The critical transmitting power and stealth imaging distance are studied. Then,technical measures for radar stealth imaging are established. Finally,the stealth imaging performances of different technical measures are verified through simulation. The simulation results show that when the radar uses a signal with a bandwidth of 30 MHz,stealth imaging can be realized at a distance of 169. 9 km for a reconnaissance receiver with sensitivity of-65 dBm.
