Abstract:

An investigation is made of automatic angle return satellite arrays for both passive and active systems. Automatic angle return arrays, called Van Atta arrays, return a signal in the direction of incidence of the impinging signal, and are effective over an angle of at least or - 45 degrees from the array axis. As a result, only partial stabilization, or single-axis spin stabilization is required, which greatly simplifies the station-keeping, orbit control problem. Further, the active Van Atta array AVA offers inherent high reliability, since many of the distributed amplifiers may fail without causing serious system performance degradation, and also because the distributed amplifier arrangements permit the use of low-power, solid state devices.
