| 摘 要： | 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。

| Abstract: | According to the design of 3 mm wave radar, an amplifier chain scheme of the coherent pulsed transmitter is proposed. The chain consists of a fundamental injection locked harmonic Gunn oscillator, a CW IMPATT oscillator and two pulsed IMPATT oscillators in cascade. In order to overcome the effect of the leak signal in the system, a new technique of suppressing the leak in the intervals of pulse by altering the frequency is created and realized in success. The developed transmitter provides the output of 5 W peak power and 30 ns pulse width in 3 mm wave with the input of 2 mW signal in 6 mm wave. |
