根据３ ｍ ｍ 波段相参脉冲雷达对发射机的要求，拟定了基波注入锁定３ ｍ ｍ 波谐波振荡器、３ｍ ｍ 波连续波雪崩振荡器和两级脉冲雪崩振荡器级联注入锁定的放大链路方案，提出并实施了“脉间异频防泄漏技术”，抑制了漏信号对系统工作的有害影响，实现了当输入电平为２ ｍ Ｗ 的６ ｍ ｍ 波信号时，３ ｍ ｍ波输出脉冲峰值功率大于５ Ｗ，脉宽约３０ ｎｓ。
According to the transmitter requirements of 3 m m band coherent pulse radar, a fundamental injection locked 3 m m harmonic oscillator, a 3 m m wave continuous wave avalanche oscillator and a two-stage pulse avalanche oscillator are cascaded to inject lock Amplify the link scheme, put forward and implement the “pulse inter-frequency anti-leakage technology” to suppress the harmful effects of the leakage signal on the system work to achieve when the input level of 6 m m wave signal of 2 mW, 3 m The m-wave output pulse peak power is greater than 5 W and the pulse width is about 30 ns.
