The application of "cat-eye" effect in real-time evaluation of laser directional jamming effect.

In order to evaluate the effect of laser interference under non-cooperative conditions, a new method was proposed to evaluate the effect of laser interference by using "cat-eye" echo intensity by the forming principle of "cat-eye effect". The influence of laser incidence angle, laser jamming power, and distance on the echo power of "cat-eye" was analyzed. The relationship between the power of "cat-eye" echo and the laser jamming effect of the photoelectric imaging system was obtained. The results show that the echo power of the "cat-eye" was mostly affected by the laser interference distance and the interference laser incidence angle, and the echo power and interference duration decreased significantly when the distance of the echo detector from the laser source exceeded 50m while jamming anti-tank missiles. It was feasible to apply the principle of "cat-eye" effect to evaluate the effect of laser directional jamming in real time. The conclusion had certain reference significance for laser directional jamming equipment. [ABSTRACT FROM AUTHOR]
