Simulation and study of windshear signal in airborne pulse Doppler weather radar

The airborne forward-looking wind hear weather radar is a sort of pulse Doppler radar, it has weather detection, turbulence detection, low-altitude wind hear detection and other functions. Considering low-level wind hear on the dangers of civil aviation, the paper studied the modeling and simulation of wind-shear wind and wind hear radar echo signal, analysis the wind hear characteristics of the echo signal model, verified wind hear detection algorithms, which is Pulse Pair Processing (PPP), calculated the dangerous risk factor of simulated signals and gives the degree of judgment, and finally through sector scan approach highlights the speed of wind shear signal characteristics.
