摘　　要：在电子对抗系统中,随着对抗领域的拓展和系统功能的提高,对发射机功率输出精准性的提高已得到越来越多的重视。在不同的功率控制方案中,数字闭环功率控制具有大动态、高精度、脉冲适应能力强、功率自动校准、不需要外部控制信号、具有自适应功能等优点。设计了一种数字闭环功率方案,通过实验验证,对0.35~2 GHz频段功放的输出功率控制精度可达到0.3 dB(r.m.s.),动态范围可达45 dB。In electronic countermeasure systems,with the expansion of countermeasures and the improvement of system functions,more and more attention has been paid to the improvement of transmitter power output accuracy.In different power control schemes,digital closed-loop power control has the advantages of large dynamics,high precision,strong pulse adaptability,automatic power calibration,no external control signal,and adaptive function.A digital closed-loop power control scheme is designed.It is verified by experiments that the output power control accuracy of the power amplifier can reach 0.3 dB(r.m.s.)and the dynamic range can reach 45 dB for the 0.35~2 GHz frequency band.
