The invention discloses an insect flapping frequency inversion method based on initial phase calculation, and relates to the technical field of radar measurement. The method comprises the following steps: establishing an insect flapping motion radar echo model containing an amplitude initial phase and a phase initial phase, and obtaining a micro-motion signal from collected insect echoes based on the insect flapping motion radar echo model to generate a micro-Doppler spectrogram; based on the micro-Doppler spectrogram, calculating an initial phase value of the phase of the insect flapping wing, and based on the initial phase value, constructing a phase compensation factor to obtain a flapping wing parameter plane; and detecting an energy peak value in the flapping parameter plane based on the phase compensation factor, and determining the flapping frequency of the insect based on the position of the energy peak value. According to the method, the phase initial phase and the amplitude initial phase are introduced, the double physical processes of wing movement and body micro movement during insect flapping are restored, a radar echo model is highly matched with a real signal generation mechanism, errors are reduced, and the anti-interference capability is improved.

The utility model discloses a bionic insect lamp which comprises an insect-shaped shell, opposite shell sliding grooves are formed in the side faces of the two sides of the inner side of the shell respectively, a swing rod capable of swinging up and down in the shell is arranged in the middle of the shell, a sector gear is arranged at the end, located on the inner side of the shell, of the swing rod, and sliding blocks are arranged in the shell sliding grooves. Racks meshed with the sector gears are arranged on the sliding block, an eccentric transmission disc and a motor are sequentially arranged on the rear side of the sliding block in the shell, wings are connected to the end, located on the outer side of the shell, of the swing rod, wing lamp strips are arranged in the wings, antenna lamp strips extending forwards are arranged at the head of the shell, and the motor drives the eccentric transmission disc to rotate. The sliding block drives the swing rod to swing, the swing rod drives the wings to swing, the swing flying action of the insect wings is simulated, the overall attractiveness and vividness are improved, meanwhile, the internal overall structure is greatly simplified, the number of parts is reduced, production and assembly are facilitated, and cost is greatly reduced.

The utility model relates to the technical field of bionic devices, in particular to a bionic flapping wing device which comprises a shell, two transmission parts, two bionic wings and a driving assembly, the number of the transmission parts is two, the number of the bionic wings is two, the two transmission parts are meshed with each other, the two bionic wings are both rotationally connected with the shell, and the driving assembly is connected with the shell. The two bionic wings are arranged in the shell and are correspondingly meshed with the transmission parts respectively, and the driving assembly is installed in the shell and drives one of the transmission parts to rotate so as to drive the bionic wings to swing synchronously through the two transmission parts respectively. According to the bionic flapping wing device, movement of the two bionic wings is transmitted and controlled through the transmission piece, the distance and the swing position between the two bionic wings can be controlled more accurately, the distance and the swing position of the bionic wings are made to better conform to the movement rule of wings of birds or insects, and the bionic flapping wing device is more convenient to use. The purpose of remarkably improving the bionic effect of the bionic flapping wing device is achieved.
