Problems solved by technology

The disadvantage of this method is that it can only be used for ordinary airborne PD radar, and it needs to rely on a SAR image to obtain the backscatter coefficient of the scattering unit. Works the way the computer system is slower

Abstract

The invention relates to a hypersonic speed platform-borne radar clutter generating system and method. The system comprises an initializing module, a numbering module, a host end and a distance ring division module of a distance ring parameter calculation module, a scattering unit clutter calculation module, a scattering unit clutter summing module, a distance ring clutter calculation module and a graphic processing unit of the distance ring clutter summing module. The method includes the steps that first, initialization is conducted; second, distance rings are numbered; third, the areas and the angles of the distance rings are acquired; fourth, the distance rings are divided into scattering units; fifth, clutters of the scattering units are calculated; sixth, the clutters of the scattering units are summed; seventh, the clutters of the distance rings are calculated; eighth, the clutters of the distance rings are summed. According to the system and method, the clutters of all the scattering units are calculated in parallel through the GPU, row guiding vectors and column guiding vectors of a foresight planar array are separately processed, the earth surface is treated as the curved surface, and the hypersonic speed platform-borne radar clutter generating system and method have the advantage of generating hypersonic speed platform-borne radar clutters fast, stability and realistically.

Description

technical field [0001] The invention belongs to the technical field of radar, and further relates to a clutter generation system and method for a hypersonic platform-borne radar in the technical field of airborne radar. The invention can be used to generate the hypersonic platform-borne radar clutter data required for subsequent signal processing, and improves the clutter generation speed. Background technique [0002] Hypersonic aircraft generally refers to winged or wingless aircraft such as aircraft and missiles flying at speeds exceeding 5 times the speed of sound. Its high-altitude and high-speed characteristics make the mounted radar face more serious clutter problems. Due to its platform characteristics, hypersonic platform-borne radar faces new problems in clutter modeling and clutter characteristics compared with ordinary platforms. The accurate modeling and generation of its clutter has important guiding significance for the research of clutter suppression . Sin...
