Research And Design In Automatic Detection System Of Bomb Explosion Position

In order to improve the shooting level of the aggressive weapon to the ground of air force, solve the problems such as Real-time character is bad, the accurate degree and the security are low which result from depending on detecting bomb explosion position artificially in the air force training of attacking the ground in the past. This paper has proposed a kind of automatic detecting scheme that use acoustics localization method as detecting principle and regard DSP as the key processor. Because of the condition of the detecting environment is bad in the field, the aural signal which waiting to be processed usually mix much noise signal, this paper combining Wavelet transform theory realize a denoising technique based on translation invariant Wavelet transform, and apply it to the signal deonising in the system. MATLAB emulation shows that the result of the signal denoising is obvious, by using the fireworks replacing bombs, we have a experiment on detecting explosion position, in a phalanx of 50m×50m, the detecting error has been control in the range of m. It have totally reached the systematic designing requirement, this system has very strong popularization and applying value.
