导航雷达是船舶安全航行的重要信息保障设备。随着固态微波电路、大规模集成芯片、全数字信号处理等技术的发展以及高技术船舶智能化、高可靠航行等新需求内涵的扩展，应用基于固态收发、脉冲压缩和全相参数字处理等技术研制的新体制船舶导航雷达已成为一种必然。比较国内外典型固态脉冲压缩导航雷达的发展现状，深入分析固态功放、数字信号产生、脉冲压缩、自适应杂波抑制等关键技术，并结合相关技术应用优势展望了固态脉压导航雷达在船舶避碰导航传统领域以及岸基目标监管、海洋环境监测等拓展领域的应用前景。
The navigation radar is the important information guaranteed equipment for ship safe navigation. With the development of the technologies such as the solid-state microwave, large-scale integrated chip and fully-digital signal processing and new requirement connotation expansion such as the high-tech ship intelligence and high reliability navigation, the application of the new-mechanism ship navigation radar based on the solid-state transmission and reception, pulse compression and fully-coherent digital processing new technologies has become an necessity. The paper compares the development status of the typical solid-state pulse-compression navigation radars at home and abroad and deeply analyzes the key technologies such as the solid-state power amplifier, digital signal generation, pulse compression, self-adaption clutter compression. Moreover this paper combines the related technology application advantages to outlook the solid-state pulse-compression navigation radar’s application prospect in the ship avoidance navigation traditional filed and the shorebased target monitoring and marine environmental monitoring field.
