RZ-70 missile ground image transmission data link is a one-to-one / one-to-two wireless data link transmission system, which includes remote terminal and ground terminal. The remote terminal is composed of missile borne antenna, missile borne video processing module and missile borne baseband / RF module. The ground terminal is composed of ground antenna, ground video processing module and ground baseband / RF module. The remote terminal can be configured as remote mode or relay mode. The remote terminal sends image information and monitoring information to the ground terminal through direct transmission (remote mode) or relay terminal (relay mode); At the same time, the ground terminal sends the control information to the remote terminal through direct transmission (remote mode) or relay terminal (relay mode). The product adopts tdd-fdd-ofdm transmission mode, adopts a variety of anti-interference and data recovery technologies such as frequency hopping, and has strong ability to resist electromagnetic interference and multipath fading; Relay mode is adopted to greatly improve the transmission distance of the system.
