Actuality. Active and semi-active optical guidance systems for projectiles and missiles at a target mainly use a laser beam from a Laser danger Warning System (LWS) designed for prompt notification of the fall of a laser targeting beam on an important protected object. Photodetectors are used to register the laser beam hitting the surface of the protected object. To reduce the likelihood of a false alarm, it is necessary to achieve the possibility of receiving the largest possible optical signal on photodetectors. Setting the task. To increase the accuracy of the generated alarm signal based on the signals of photodetectors detecting direct laser beam hits, it is proposed to install additional remote photodetectors for recording reflected and diffusely reflected optical signals. Method. The problem of optimal selection of the ratios of distances from the laser to the target and from the target to additional receivers in LWS with remote photodetectors has been formulated and solved. Two subtasks are formulated: in the first, the target indicated by the laser belongs to the enemy, and in the second, the opposite side. It is shown that when optimizing systems of laser-guided missiles and projectiles, taking into account the LWS introduced by the enemy, it is possible to use the theory of the Laser Detection and Ranging (LADAR) systems. The result is that the application of the theory of radar systems has made it possible to optimize the functioning of the attacking side in terms of optimal choice of the distance to the enemy using the LWS with remote photo sensors.
