Abstract

Abstract

This paper proposes a new flexible method of the beam shaping based on superposition principle and the scanning principle of phased array antenna. We designed a 145cm*48cm array composed of microstrip patch elements with the wavelength of 24cm. In the azimuth direction, the pattern of this array has 23 half-power beam width. According to the principle of the synthetic aperture, the azimuth spatial resolution of the strip SAR is improved dramatically with wide exam. In this paper, the wide beam antenna array is used as the antenna of an airborne SAR with ultrahigh azimuth resolution. The parameters of the antenna and the SAR system are calculated and are compared between the strip-mapping SAR and the Spotlight SAR.
