摘要 逆合成孔径雷达(ISAR)是一种高分辨率的微波成像系统,它能够对运动目标进行精确成像。现介绍了线性调频信号,论述了ISAR成像的数学模型,并对ISAR成像的原理进行了详细的介绍,然后将线性调频信号应用于ISAR成像模型中,最后建立仿真平台,实现了对目标的成像。 Inverse synthetic aperture radar(ISAR) is a high-resolution microwave imaging system,and it can have an accurate imaging on the maneuvering targets.This paper analyses LFM signal,and discusses on the principle of ISAR imaging in detail.At last,it sets up a simulation platform using LFM signal for ISAR imaging on the maneuvering targets.
