Abstract:

A number of satellite radar altimeter designs have been proposed for the purpose of remotely sensing ocean surface parameters. A precision goal of 10 cm is commonly stated to fulfill the major desires of geodesy and oceanography. An altimeter design approach is discussed that requires only a few watts of peak transmit power, a particular advantage in satellite use. A burst programmed, phase-coded waveform is proposed with an effective compression ratio of 4096, which allows a significant power reduction over previous designs. A design capable of implementation with proven devices is achieved, requiring no new developments. At the same time, flexibility is achieved, and several variations of the basic waveform are discussed with differing levels of performance, complexity, and power consumption. Author
