The effectiveness of frequency domain processing algorithms in bistatic SAR depends on the accuracy of approximations used for the derivation of the bistatic point target spectrum. This paper presents a modified bistatic point target spectrum based on the 2 dimensional principle of stationary phase with the accuracy improved by the use of a Chebyshev polynomial approximation. The performance of the new method is compared to the conventional Taylor series approximation approach in the approximation of the range-azimuth frequencies coupling variable. The new approach is shown to provide a more accurate approximation reducing the phase error. The accuracy improvement is shown to yield a more accurate spectrum that can be exploited in bistatic SAR focusing algorithms, improving their accuracy and efficiency. (5 pages)
