Abstract

The invention discloses a pulse laser transmission characteristic simulation method in a flying dust environment, and belongs to the technical field of numerical simulation. The simulation method comprises the following implementation steps: establishing a coordinate system, dividing flying dust mass concentration intervals, calculating corresponding laser attenuation coefficients of laser in different mass concentration intervals, setting flying dust environment parameters, pulse laser emission system parameters, back scattering echo receiving system parameters and transmission receiving system parameters, initializing emitted photons, calculating the free scattering path of the photons, correcting the free scattering path, and calculating the positions and energy of the photons after scattering; and judging the position of the photon in the coordinate system, counting photon information received by the transmission receiving system and the back scattering echo receiving system, and finally shaping the photon information into a pulse signal. According to the method, the detection characteristics of the pulse laser fuze in the complex battlefield dust raising environment can be effectively simulated, and a theoretical basis is provided for improving the detection performance of the pulse laser fuze.

Description

technical field [0001] The invention belongs to the technical field of numerical simulation, and in particular relates to a simulation method for pulse laser transmission characteristics in a dusty environment. Background technique [0002] Pulse laser fuze is a device that uses pulse laser for short-distance detection. It has the advantages of high precision control of explosion point and strong anti-electromagnetic interference ability. It has been widely used in various weapon systems. However, pulsed laser fuzes are susceptible to scattering and absorption by battlefield dust particles, resulting in a decrease in detection performance. Due to the variety of dust particles in the battlefield and the complex distribution of spatial mass concentration, there is currently no effective method for simulating pulsed laser transmission characteristics in combination with the spatial mass concentration distribution of dust. Contents of the invention [0003] In view of this, t...
