Active omnidirectional buoy detecting signal simulation based on FPGA

Active omnidirectional buoys detecting signal simulation technology was studied and the system was implemented, a means for the field testing calibration machine buoy search system was provided. With FPGA as the core, the signal generation algorithm module and target strength set algorithm module were designed and active omnidirectional sonobuoy emission signal simulation was designed. By superposition of target strength, Doppler frequency shift of submarine target information, the simulation of active Omnidirectional sonobuoy detecting signal was realized. An experiment system had been set up, the generated CW signal and LFM signal were tested and the experimental results showed that simulation of active Omnidirectional sonobuoy detecting signal performance was good, the research contents of this paper have very definite military application value.
