A new microwave imaging method for earth observation

Microwave imaging techniques which can provide all-weather, day-and-night imag-ing capability have important applications to many scientific fields. It is an active area to ex-plore new microwave imaging ideas, systems and techniques. In this paper, a new microwave imaging method for earth observation is proposed. In this method, the signal transmitter and receiver are located in different platforms, and only a monochromatic microwave is required to illuminate the earth surface. Numerical simulation results show that this method can produce a microwave image with high spatial and radiation resolutions.
