Abstract

The invention discloses an unmanned aerial vehicle group target detection method, electronic equipment and a storage medium. The method comprises the steps of obtaining an echo signal of an inter-pulse quadrature phase code of a to-be-detected target; performing pulse compression, digital beam forming and slow time dimension fast Fourier transform on the echo signal to obtain Doppler angle data; and judging a to-be-detected target according to the Doppler angle data, and when the to-be-detected target is a group target, performing group target parameter and number estimation to obtain the target number and target parameters of the to-be-detected target. The method can be applied to actual engineering, and the purpose of meeting the low-cost requirement of the MIMO radar almost without increasing hardware complexity is achieved.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a method for detecting an unmanned aerial vehicle group target, electronic equipment and a storage medium. Background technique [0002] With the continuous development of drone technology, the use of low-cost drones for terrorist activities will pose a great threat to public safety. Moreover, the development of collaborative technology and artificial intelligence has promoted the derivation of drone swarms and increased the pressure on existing monitoring and early warning systems. Therefore, the ability to detect group targets is an active and effective early warning and defense for existing security systems to protect people's property. Security is a key link in grasping the initiative of counter-terrorism. [0003] MIMO radar adopts wide-beam and long-term observation methods. Compared with traditional tracking-while-scanning radars, there is no pressure on multi-tar...
