  • The range migration of the airborne bistatic SAR is determined jointly by its geometric configuration and the motion parameters of the transmitter and receiver, so it has two-dimensional space-variant properties under general configuration. The space geometric model of the airborne bistatic SAR for general configuration is firstly proposed. Via Taylor polynomial expansions to the bistatic range, the expressions of the range walk and range cure in time domain are derived. Making use of the uncoupling expressions both the transmitter range and the receiver range, the range cure compensation condition is derived. By simulations, the variant properties of the range migration and the asymmetry variant characters of the residual range cure after the migration compensation are validated.
