Synthetic aperture radar system for continuous wide swath high resolution imaging and method thereof

摘要

This invention relates to synthetic aperture radar system and method for implementing continuous wide-area high-resolution image , different channels, the carrier frequency for each channel is applied to the plurality of antennas, each transmitted signal is assigned to perform each of the linear frequency modulation, the signal to each of the linear frequency modulated continuous observation area through the antenna into a pulse form modulator to be transmitted, the plurality of signals to generate a wideband signal and the wideband Doppler Mole (chirp) signals using the received signal of the observation area via an antenna synthesis section, wideband and broadband Doppler signal from the signal synthesis unit using a mole constituted by resolution signal is calculated to calculate the resolution. Thus, according to the present invention can be improved maintaining the continuity characteristics and a wide area and a long detection range of the image and at the same time the resolution of the azimuth direction and the distance direction at the same time. ;
