Abstract

Adaptive processing of microwave sea echo is proposed for the suppression of strong reflections from scatterers on the ocean surface. An adaptive method using echoes of pulses at different carrier frequencies is also shown to be effective for this purpose. It is noted that nonadaptive processing of the same data does not suppress these reflections. Results obtained by processing coherent microwave backscatter from the ocean surface are presented
