Abstract：The characteristic of the echo of the wide swath airborne Synthetic Aperture Radar (SAR) is analyzed, then the expression of the shaped beam radiation pattern in the range plane of antenna is induced . The pattern is synthesized using the Schelkunoff unit circle method with null filling, and the exciting amplitude and phase of the 5 elements are given. The two sample microstrip arrays with different dielectric are fabricated, and the measured results are basically in accordance with the simulated and synthesized results. The valid conclusion of the synthesized and realized the shaped beam pattern can be drawn and the technology route is feasible.
