The bistatic image formation process is more complex than the monostatic one, because the bistatic range equation consists of the sum of two hyperbolas. Several bistatic SAR processors have been presented in the last years. One of them is the bistatic range migration processor, which will be evaluated in this paper not only with regard to translational invariant configurations but also in view of variations from a model assumption. The bistatic range migration processor will be compared with a bistatic generic time domain SAR processor. The processing quality will mainly be evaluated by measuring the resolution and PSLR of point target responses.
