Title:
RADAR PROCESSING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/195297
Kind Code:
A1
Abstract:
The present invention is provided with: a radar sensor (1) that repeatedly radiates a chirp signal into a space while changing the change rate of a frequency for the chirp signal, receives the reflected wave of the chirp signal reflected on an object, and outputs the reception signal of the reflected wave; and a signal processing unit (2) that corrects misalignment of an image forming position of the reception signal, the misalignment occurring accompanying the movement of the radar sensor (1), and reproduces an SAR image from the misalignment-corrected reception signal. The signal processing unit (2) converts the reception signal of the reflected wave into reception data in a frequency space, corrects the misalignment of the image forming position of the reception data in the frequency space for each change rate of the frequency in the chirp signal, returns the reception data to a signal of a time domain, and combines the signals of the time domains at the respective change rates.
