摘要

本文介绍了X波段泛在雷达射频子系统的设计。本文主要介绍天线和接收机的设计。无所不在雷达是一种新颖的系统,它用一根发射天线照亮一个巨大的覆盖范围,同时通过一组指向同一区域的天线接收来自目标的回波。总结了接收天线的主要特性以及它们的设计和辐射方向图的测量。最后给出了各接收机的框图,并与仿真结果进行了对比。

Design of radio frequency subsystems of a ubiquitous radar in X band
The purpose of this paper is to present the design of the radiofrequency subsystems of a ubiquitous radar in X band. This document is focused on the design of the antennas and the receiver. Ubiquitous radars are novel systems that illuminate a huge coverage with a transmitting antenna while receiving echoes from targets by a group of antennas pointing to the same area. The main characteristics of the receiving antennas are summarized as well as their design and measurements of radiation patterns. In the last part of the paper, the block diagram of each receiver is shown and measurements are compared with simulations.
