Abstract


UAV landing by GPS and the altimeter to provide accurate positioning data to guide its safe landing. However, in the combat GPS susceptible to interference, under such conditions can be effectively recycling the landing radar, UAV. The issue is to single pulse landing radar, unmanned aerial vehicles against the background of development of three-channel digital IF receiver hardware platform and to design the display to complete the entire radar system control program, the hardware platform developed by the circuit in addition to completing three-channel digital IF receiver functions, also integrates unmanned aerial location coordinates solver, heading angle calculation, thus greatly improving the system integration and reliability. This article reads as follows:1. Designed a dedicated digital IF receiver based on AD6652, Xilinx’s V4 Series VC33 Series FPGA and TI’s DSP-Digital IF receiver circuitry. The circuit implementation of the three-channel 60MHz intermediate frequency analog signals (bandwidth of 1MHz) of sampling and digital down conversion, extraction and filtering, while completing unmanned aerial location coordinates solvers, computing and other functions such as heading angle, the end result through the RS422 interface, output, send a total control computer display;2. Established unmanned aerial position solver, drop angle and heading angle digital models, and accuracy of mathematical model analysis;3. The completion of the entire radar system, the display control procedures programming and debugging.
