摘要
任何无线电发射设备在发射有用信号的同时,都会附带一些无用发射,无用发射除了杂散发射以外还包括大量的带外发射。文中介绍的脉冲雷达频谱控制方法是通过对发射信号的时域脉冲进行整形,来抑制由于调制产生的带外发射。试验结果表明,该方法能够有效地抑制以速调管为末级功率放大器的脉冲雷达的带外发射。
While amplifying useful signals,every radio transmitting equipment will produce some unuseful emissions,these unuseful emissions include a large number of out-of-band emission besides spurious emission.The spectrum control method for pulse radar is introduced in this paper in order to inhibit out-of-band emission which results from modulation process through shaping time-domain pulse to transmitted signals.Experimental results show that the method is effective on inhibiting out-of-band emission which the last stage power amplifier of pulse radar is klystron.
