Studying The Signal Processing Technology Of Airborne Forward-looking Windshear Weather Radar

The airborne forward條ooking windshear weather radar is a sort of microwave Doppler radar.Jt has weather detection, turbulence detection,windshear detection and other functions.For engineering application, the signal processing technology of airborne forward條ooking windshear weather radar system is studied in this composition.The contents include signal processing methods for weather, turbulence and windshear targets.The emphasis in this composition is windshear signal processing technology. Some processing methods are introduced in detail, they are suppressing clutter,extracting windshear parameters,computing hazard factor and etc..The signal processing simulation is accomplished on computer, it includes simulating microburst echo signal,simulating ground clutter echo signal,filtering clutter,estimating wind speed and calculating hazard factor.From the simulated results,a dangerous windshear is detected 5O~78s, so the radar performance meets the certification requirements proposed by FAA and NASA.
