Research on the Azimuth Ambiguity of Phased Array Sliding Spotlight Mode SAR
The azimuth ambiguity is a key character to scale the image quality,but the traditional expression in strip-map SAR does not match the situation in sliding spotlight. This paper firstly introduces the azimuth ambiguity expression of strip-map SAR. Then focusing on the phased array sliding spotlight condition,analyses its working principle,aims at the characteristic that antenna patterns are changed continuously in the process of beams sliding,constructs the azimuth ambiguity calculation function of phased array sliding spotlight SAR,makes corresponding system design and simulation farther,provides effectual reference for SAR system design.
