Abstract
The results of investigation of the resource management in radar search are presented in the paper. The time for search of manoeuvring targets is minimized by optimal distribution of radar power among the space directions and by optimization of search parameters.
The problem of the optimal control of radar search is extremely complicated in the general case and in real situations, therefore we have compared only some strategies (e.g., one stage cyclic strategy, various multistage strategies).
In some simple cases (e.g., motionless targets) optimal parameters of multistage strategies maybe found but in the general case the efficiency of strategies may be evaluated with the help of statistical simulation. The simulation time was essentially reduced by some simplifications of models, by the forecast of discrete coordinates of the targets and by the use of averaged values.
The usage of the proposed strategies enables us to reduce the time of search by 2–3 times. Those strategies may be executed in real time.
