Airborne meteorological radar detection waveform design and display method

Abstract

The invention provides an airborne meteorological radar detection waveform design and display method. The method comprises the following steps: step 1, composite pulse width waveform design of meteorological detection; step 2, acquiring meteorological detection data of a composite pulse width waveform according to the composite pulse width in the step 1; and step 3, carrying out nonlinear weighted fusion on the meteorological detection data in the step 2 and obtaining detection echo data. Different pulse widths in the composite pulse width waveform design are utilized to meet long-distance and short-distance meteorological detection requirements, and different pulse width reflectivity factor data are fused through nonlinear weighting to obtain a long-distance full-range high-precision radar target display picture. The method is simple and effective to realize, the result picture is clear and natural, the target detection and alarm display functions of the airborne meteorological radar can be improved, and the flight safety is improved.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to an airborne weather radar detection waveform design and display method. Background technique [0002] Airborne weather radar is to install the weather radar on the aircraft to detect and warn the weather conditions in front of the aircraft, so that the aircraft can detect dangerous weather in time, choose a safe route, and ensure the safety of the people on board. The flying speed of the plane has reached hundreds of kilometers per hour, and the flying distance has reached thousands of kilometers within a few hours. The meteorological conditions in the flight area are changing rapidly, and due to the large flight range and long distance, the meteorological conditions in various places are complex and changeable. If early warning cannot be achieved, it will cause great harm to the safety of the aircraft. Therefore, airborne weather radars are required to have long-distance detecti...

AI Technical Summary

Problems solved by technology

If early warning cannot be achieved, it will cause great harm to the safety of the aircraft.

Therefore, airborne weather radars are required to have long-distance detection capabilities. Long-distance detection capabilities require weather radars to use large pulse width detection waveforms, but large pulse width weather detection waveforms usually bring large short-range blind spots, resulting in Meteorological hazards in the vicinity of the aircraft cannot be effectively detected and identified, which will greatly endanger the safety of the aircraft
