Abstract :
A study has been conducted to establish the design parameters of a radar system to determine satellite ephemeris through accurate estimates of range and range rates of very high altitude satellites. The aim has been to replace a requirement for high average transmitted power by signal processing carried out over extended time intervals. It has been concluded that, to accommodate satellites with a radar cross section of 10 m/sup 2/, the radar´s peak transmitted power at X-band must be at least 1 kW, and preferably 5 kW. The required range and range rate accuracies are 1 m and 0.01 m/s, respectively. The coherent integration time may be as large as 200 s.<>
