Sparse Jungle DBS Imaging Method and Simulation of Radio Fuze
In order to overcome the problem of insufficient imaging capability of ground-strike radio fuzes for sparse jungle terrain,radar imaging technology was applied to ground-strike radio fuzes,and a Doppler beam-sharpened imaging and simulation method of fuzes for sparse jungle was proposed.Firstly,the geometrical rela-tionship of radio fuze swooping attitude imaging was analyzed.Then,a computer simulation model was estab-lished for the trees,and then the simulated echo data was obtained.Finally,algorithmic operations such as dis-tance-directed compression,Doppler center estimation,distance-walk correction,and pitch-directed fast Fourier transform were implemented on the echo data to obtain the Doppler beam-sharpened imaging simulation results of the radio fuze for sparse jungle.The proposed imaging method was validated by constructing several sparse jungle undulating terrain scenes in the computer.The simulation results showed that the proposed imaging method had good effecton the imaging of sparsejungle,and provided data support for the development of intelli-gent recognition algorithms of topography and geomorphology for fuzes,and promoted the development of the i-dentification and destruction technology of radio fuzes used in earth strikes.
