摘　　要：射频暗室仿真试验具有保密性好、信号模拟逼真度高、代价低和可重复性好等优点,尤其在重构复杂电磁干扰环境方面具有不可替代的作用。以反舰雷达导引头抗电磁干扰为应用背景,详细介绍了射频暗室内如何等效重构实际电磁环境的方法,推导了目标、有源干扰、面杂波和体杂波的等效重构雷达方程,并介绍了射频暗室仿真时不同干扰模式的相应干扰策略。Simulation tests in RF（radio frequency） anechoic chamber with good confidentiality, signal analog fidelity, repeatability, low price and other advantages especially play an irreplaceable role in the reconstruction of the complex environment of electromagnetic interference. Based on the anti-electromagnetic interference of the anti-ship radar seeker, how to reconstruct the actual equivalent electromagnetic environment in the anechoic chamber is detailed introduced, and the equations of the target, active jamming, surface clutter and volume clutter radar are deduced for the equivalent reconstruction. The corresponding strategies for the different interference patterns in the anechoic chamber are also introduced.
