机载雷达2kW大功率发射机的研究

A Study on High Power Airborne Radar Transmitter with Average Power of 2kW

由于机载雷达要求越来越高,要求发射机的体积小、重量轻,但输出功率高,时域特性和频域特性好,发射机不仅要在技术上突破,增加功率密度,还必须促进基础、核心器件研制。文中从研制平均功率2 kW大功率机载雷达发射机的实际出发,介绍了发射机的设计思想,以及重点和难点的解决。

The requirements on transmitter from airborne radar system are higher, such as higher. The smaller size, less weight, high output power, good time and frequency domain properties. Therefore, the transmitter need not only get breakthrough in tech- nology to increase the power density, but also promote the development of the basic and key components. The discussion in this article is from the practical situation of the design and manufacture of high power airborne radar transmitter with average power of 2 kW, pointing out the design principle of the transmitter and the settlement of the emphases and difficulty.
