独立双基地雷达具有许多独特的优点和潜在能力。独立的双基地雷达接收系统协同非配合的发射站工作的时间同步信息和发射波束指向信息可以从接收信号中提取。本文论述作者所研制的非相参独立双基地雷达接收系统的结构、原理、同步精度和试验运行概况,详细介绍获取上述同步信息的方法和关键技术的解决办法。本文最后提出一种将数字波束形成(DBF)技术与独立双基地同步系统相结合的新型独立双基地雷达系统的结构和特点。
The independent bistatic radar has many unique advantages and potential capabilities. The independent bistatic radar receiving system cooperates with the non-cooperative transmitting station to work the time synchronization information and the transmitting beam direction information can be extracted from the received signal. This article discusses the structure, principle, synchronization accuracy and experimental operation of the non-coherent bistatic radar receiver system developed by the author. The methods and key technologies for obtaining the above synchronization information are introduced in detail. At the end of this paper, we propose a new type of bimodal radar system combining the digital beamforming (DBF) technology with an independent bistatic system.
