Delay-Doppler Maps study over ocean, land and ice from space

This work analyzes the properties of the Delay-Doppler Maps (DDM) derived from the limited experimental data freely available from the UK-DMC. The quality of the received signal over ocean, land and ice is evaluated. In this study the minimum number of incoherent integrations after 1 ms basic coherent integration that are needed to obtain a quality DDM over each surface type is determined using three different techniques: studying the volume of the DDM against the incoherent integration time, observing the signal-to-noise ratio of the signal, and finally analyzing two pixels of the DDM, the maximum and another one noisier, and performing histograms of these points as a function of the incoherent integration time.
