| With the rapid development of laser technology, semi-active laser homing weapon system is widely used in the military field, the system is normally provided by the laser irradiation, a seeker and guided munitions components. Irradiator transmit pulse laser irradiation target, according to the irradiation spot seeker identify targets to guide the missile target. Visible laser irradiation spot characteristics and semi-active laser homing weapon hit rate are closely related.In this paper, the principle of laser radiation from the test characteristics of the starting spot on the energy density characteristics of the test conducted in-depth research. Designed a fast accurate measurement of the size of the test system and the energy density distribution, the test system includes the airborne radiation, laser energy is diffuse reflecting target, close to the energy density distribution of the test system, the energy density of the test system of the remote and a wireless communication system. Where the energy density distribution of the test is to test the contents of the main energy distribution, mainly affecting the accuracy of the missile guidance; energy density value of the test include the size of the diffuse energy, pulse frequency and pulse code coding accuracy, mainly affecting the ability to identify the target seeker. ZEMAX software applications were close to the energy density distribution on the test system and remote test system energy density optical system design. Solidworks design software applications to complete the energy density of the test system. |
