ABSTRACT:
A method of operating a SAR system comprised of emitting a sequence of pulses toward a target, alternating characteristics of pairs of successive pulses, receiving reflected pulses from the target, passing the received reflected pulses through a filter, modifying parameters of the filter in step with the transmitted pulses to match the characteristics of the successive pulses in the event a time delay between pulse transmission and reception of a pulse reflected from a target is a fraction greater than an even multiple of a pulse period, and modifying the parameters of the filter in anti-synchronism with the successive pulses in the event a time delay between pulse transmission and reception of a pulse reflected from a target is less than a fraction greater than an even multiple of a pulse period.
