Abstract :
A spaceborne radar for atmospheric observation must be able to detect atmospheric backscatter in the presence of clutter due to antenna sidelobes. Here, we analyze the problem in detail, deriving a method for computing clutter which includes the effects of all contributing transmit pulses, Doppler shifting, finite receiver bandwidth, and the curved Earth´s surface. The results are applied to analysis of existing radars and design of future radar systems
