Abstract
Time-reversal radar imaging takes advantage of concepts based on time-reversed wave propagation to improve object resolution when these objects are located in a complex environment. There exists a multitude of propagation paths, making their imaging difficult. However, multipath can also be used to enhance the object location and shape. In the case of synthetic aperture radar (SAR) imaging, multipath can also increase the effective aperture without additional spatial samples.
