Simulation, radar, scheduling algorithm, and task.


Radar systems require complex implementation and tests that not always are available for researchers. That is why modelling and simulation methodologies are often necessary to perform radar processing algorithms. These skills are effective such as for realizing the design, model and experiments, and as for the validity of the obtained results. The radar that has been developed is multifunction radar, MFAR (Multi-Function Array Radar), which joins inside the same system, and simultaneously, the classic functions of tracking and surveillance, and all the functions related to the communication, countermeasures, and calibration. All these functions constitute the tasks to execute. The task scheduler is a key element of the radar, since it realizes the planning and distribution of the energy and time resources to be shared and used by all those tasks. This paper presents schedulers based on the use of task queues. Multiple schedulers have been designed and studied, and it has been realized a comparative analysis of the different performed schedulers. A specific software tool has been designed and developed to perform the radar system, and to do all the experiments. An appropriate set of radar characteristics has been selected to evaluate the kindness of the task scheduler working.
