Abstract :
This paper investigates the inverse matrix of near-space elevation multi-aperture synthetic aperture radar(SAR) wide-swath remote sensing. Note that near-space is defined as the altitude region between 20 and 100 km, which is much higher than air-borne height, and much lower than space-borne height. Besides, the flight speed of near-space aircraft is between air-borne aircraft and space-borne aircraft. This provides advantages for realizing high-resolution and wide-swath imaging, compared to air-borne and space-borne SAR. In this paper, the relationship between conditional number and system design specifications are analyzed. Simulation examples and simulation results are also provided.
