摘　　要：自行研制冲激雷达实验系统,其关键技术包括多路相干合成脉冲源、正交解调采样接收机、信息处理机和收发天线阵列等。并用该系统在外场开展了隐身目标探测实验。实验结果表明,冲激雷达有较强的反外形隐身和材料隐身的能力。The research is based upon a self-developed impulse radar experiment system, whose essential technologies include multiplex correlative pulse combining pulser, quadrature demodulation sampling receiver, signal processing system and pulse radiating and receiving army antennas and so on. The detection experiment of stealthy targets in the outdoor was carried out by the system. Its results indicate that the impulse radar has the powerful capability of anti-shape stealth and anti-material stealth.
