Two Dimensional Phase Integration for Radar Image Formation

摘要

Radar imaging traditionally requires extremely large computational resources in order to coherently process data into an image due to the large number of data samples in high bandwidth radars. We propose a methodology to achieve high range and cross range resolution by pre-detection followed by phase integration in the wavelet domain in order to significantly reduce the bandwidth necessary and the computational load of the coherent phase processing. We will then compare this process to FFT based phase integration in terms of computational complexity and show simulated results.
