ISAR外场数据采集实验及数据处理

逆合成孔径雷达是一种具有极大宽带的相干雷达,能从固定或运动平台对导弹、飞机等运动目标进行全天候、全天时、远距离成像,因而,是极有前途的一种目标识别手段。本文主要介绍逆合成孔径雷达外场数据采集实验系统及其回波数据采集方法。最后,给出了数据处理结果。

ISAR Data Sampling and Processing

Inverse synthetic aperture radar (ISAR) is a kind of coherent radar with very wide band,which can provide all-weather,all-day,long range imaging for moving targets such as missiles and aircraft from a fixed or moving platform. It is a most promising approach for target i-dentification. Data sampling system architecture and approach of ISAR are introduced in the paper. Finally, the results of data processing are given.
