Design of Radar Electromagnetic Environment Simulation System Based on Altera Stratix? III Series FPGA

摘要

Radar signal sorting in complex electromagnetic environment is the key technology of radar reconnaissance interference, which plays an important role in the measurement, analysis and identification of subsequent radar characteristic parameters. Aiming at the fact that the field experiment can not simulate the complex electromagnetic environment and the huge cost of the real battlefield, a radar electromagnetic environment simulation system based on ADC/DAC+FPGA+ARM architecture is proposed, which realizes the embedded electromagnetic environment The simulation and design of the simulation system are carried out, and the RF noise module, the random pulse module, the linear sweep module, the pulse delay superposition interference module and the single batch false target module of the electromagnetic environment simulation system are simulated.
