Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Measurement of the Doppler velocity of distributed targets, such as precipitation and rough surfaces, from space is challenging due to the large platform velocity, the broad Doppler spectrum, and the resulting decorrelation beten pulses. A previous paper by Durden  et al.  suggested the use of the displaced phase center antenna (DPCA) technique for the Doppler measurements of such targets. The proposed technique uses two antennas with appropriately chosen pulse timing to cancel platform motion. While DPCA has been used for many years in canceling clutter for point target motion measurements, its use in measuring Doppler from distributed targets was not ll established. Here, the authors provide an example of surface measurements from a dual-antenna airborne system and a first demonstration of the use of DPCA to estimate the surface Doppler.
