This paper extends our theoretical and experimental researches on microwave backscattering at small incidence angles as applied to remote sensing of the ocean. A new concept of a Doppler radar with a knife-beam antenna pattern is proposed. With a nadir-pointing rotating antenna the radar will be able to measure a number of key sea state parameters previously unavailable, such as the long wave slope, the direction of wave propagation. Preliminary theoretical analysis and numerical simulations predict that in a space-borne scenario, signals may be isolated for scattering cells of the order 14×14 km over a swath approximately 250 km wide.
