| 英文摘要 | This paper first shows the 3-d property of bistatic synthetic aperture radar (bisar) geometry, which clarifies that the algorithms for bistatic sar should be deduced in 3-d space. it then models the bistatic echo according to the 3-d geometry and obtains the signal spectrum in the wavenumber domain. based on the spectrum, the formula for the wavenumber-domain interpolation of the omega-k algorithm is deduced, and the residual phase is obtained. then, the impacts of the residual phase, including position displacement, range, and azimuth defocusing, and a constant phase for each pixel, are explicated. finally, the simulating results exhibited at the end of this paper validate the correctness of the analysis and the feasibility of the algorithm. |
