Based on Orthogonal Frequency Division Multiplexing (OFDM) technology, a joint design method of unmanned aerial vehicle (UAV) multi-carrier radar detection and orthogonal frequency reuse high speed communication is proposed. The probing and communication function module is designed, the working mode of transmitting and receiving state is expounded, and the design of simultaneous and agile probe waveform of the polarization frequency is given. Performance simulation results verify the feasibility of joint design of multi-carrier detection and simultaneous polarization and frequency agility technology. Combining wideband detection, simultaneous polarization, frequency agility, multi-carrier communication, adaptive communication, etc., And high-speed communication dual-task at the same time, to meet the multi-UAV system integration, miniaturization, low power consumption, low-cost needs.
