Modified keystone processing algorithm for the space-based bistatic radar systems

The bistatic keystone processing algorithm was presented in the paper to increase the coherent integration time of the echo signal scattered from the moving target in the space-based bistatic radar systems. The high speed of receiver has a severe impact on the target detection of the system. Therefore, the echo of the central target was selected as the reference signal to remove the undesired impact of receiver in the target detection of space-based bistatic radar systems. The simulation results validate the proposed algorithm.
