摘要
针对相参雷达和非相参雷达的概念进行阐述。通过详细分析两种体制雷达在应用上的主要区别,侧重介绍相参雷达的优点。相参性方面重点介绍多普勒效应具有的特性,从信号接收和信号处理上重点讨论了相参性雷达拥有的速度测量功能,在速度模糊和距离模糊上详细比较了两者的差别。通过实践证明,相参雷达的应用范围比非相参雷达的范围广阔得多,但价格不菲。
The concept of coherent and non- coherent radar is explained. Through a detailed analysis of the two systems on the radar, the main difference in the application, focusing on the advantages of coherent radar. Coherent Doppler effect in terms of highlighting has characteristics of the signal received and a letter from a good treatment focused on the coherent nature of radar,owned by the velocity measurement function, in terms of speed and distance blur on a detailed comparison of the differences between the two. Practice has proved that through the application of coherent radar, which has wide range than noneoherent radar.
