One of the perspective options for constructing laser object management systems are raster-type systems in which the temporal position of the pulse is used as information about the spatial location of the object in the target raster relative to the moment of the scanning start of the sector in which the object is being directed.
The functioning of the automatic laser-beam guidance system (LLSN) of missiles, as a rule, occurs under conditions of exposure to both unintended (atmospheric) and intentional optical interference. Earlier, mathematical models were developed and an estimation of the efficiency of automatic LFSM operation in the conditions of laser retransmission interference, as well as masking aerosol interferences, interrupting the control signal of the rocket during the entire time of the rocket flight to the target. However, the creation of masking aerosol jammers in the laser channel of remote control of a rocket can not lead to an interruption of information in the control loop during the entire duration of the interference, but only to the skipping of a part of the signals. The effect of such interference on the operation of automatic laser-beam telecontrol systems was not previously considered.
A mathematical model of the system of automatic laser-beam guidance of a hypersonic guided missile in the conditions of skipping a part of signals is developed. The resulting set of simulation results allowed us to investigate the effect of control signal skipping on the quality of this remote control system.
