Abstract


In recent years , China's laser proximity fuze technology development rapidly. The proximity fuze technology , the range accuracy is the proximity fuze important performance indicators . It is a missile control , bomb burst point play to guarantee maximum damage efficiency . Laser proximity fuze requirements of high - speed movement of the target of a few meters to tens of meters for precise distance and precise positioning to improve target detection capability ; requirements to improve the hit rate of the weapons that are resistant to all sorts of interference . In this context , the paper from the increase pulse proximity fuze scheduled departure from the precision laser proximity fuze Distance algorithm to study through theoretical analysis and experimental verification . In terms of design theory , this subject first dynamic set of four laser distance mechanism analysis comparison, the selection principles of different fixed pitch mechanism . Transmitted signal and the echo signal spatial and temporal distribution of the laser , the reflective properties of the different target echo waveform broadening and distortion , theoretical analysis and the establishment of the transmitted signal and the echo signal in the case of the mathematical model of the algorithm the design provides a theoretical basis . Technology , the subject first analysis of the traditional analog approach , then of several digitized approach algorithm simulation , and each algorithm error statistics . By comparing the statistical results , analysis , design a wavelet transform method pulse mexh Laser Distance technology , and the development board test , measurement results are consistent with the actual results . Finally, the hardware platform , the principle of verification , calibration and measurement results . The experimental data show that the technology can be fine determine the distance of a few meters to tens of meters of the target , and effectively reduce the noise interference , thereby improving the speed and accuracy of laser fixed pitch .
