A bistatic chirp scaling algorithm (CSA) is presented to process the forward‐looking bistatic synthetic aperture radar (FL‐BiSAR) data. First, the double‐square‐root equation in the general bistatic range model can be simplified to a square‐root equation, when the size of the scene is small enough. Based on the model, the range Doppler spectrum is derived. Then, a CSA is obtained. The range model is proved to be an effective proxy by a simulation.
