A New Modulation Technology for Range Safety Remote Control System
Sun Dongzhi (Beijing Research Institute of Telemetry)
High Alphabet modulation is a new modulation method, which is very suitable for safety remote control aboard missile, launch vehicle, manned or unmanned spacecraft, etc. In this paper, the primary principle is discussed in view of range safety system, moreover, the noise suppression of HA is simply analyzed in theory. In the simulation, the transmission and demodulation of all digital HA safety subcarrier signal is realized. The simulated test result of noise suppression performance of HA is conformed to the theory.
