摘要

国产可运输C波段跟踪雷达是一种4D雷达,提供距离、方位角、仰角和多普勒单脉冲跟踪数据。该雷达是基于最先进的数字技术设计和开发的,其中包括基于FPGA的数字接收机。对于远程应用,这类雷达采用基于磁控管的发射机,因为需要高峰值功率。然而,对于这些基于磁控管的低PRF(脉冲重复频率)雷达来说,提取目标的第四维(4D)即多普勒频率并不是一种简单的方法。本文介绍了实现高精度多普勒测量的设计和开发特点。

A Novel Scheme of Doppler Measurement for Magnetron Based C-Band Tracking Radar
The Indigenous Transportable C- Band tracking radar is a 4D radar providing Monopulse track data in Range, Azimuth, Elevation and Doppler. The Radar has been designed and developed based on state of the art digital technologies which include FPGA based Digital Receiver. For long range application, this class of radar employs a magnetron based transmitter due to the requirement of high peak power. However, extracting the fourth dimension (4D) of the target, i.e. the Doppler frequency is not a straight forward method for these magnetron based low PRF (Pulse Repetition Frequency) Radars. This paper describes design and development features which result in high accuracy Doppler Measurement.
