EVALUATION OF RADAR TASK SCHEDULING ALGORITHMS BASED ON SIMULATION METHODOLOGY

摘要

Radar systems require complex implementation and testsrnthat not always are available for researchers. That is whyrnmodelling and simulation methodologies are oftenrnnecessary to perform radar processing algorithms. Thesernskills are effective such as for realizing the design, modelrnand experiments, and as for the validity of the obtainedrnresults.rnThe radar that has been developed is multifunctionrnradar, MFAR (Multi-Function Array Radar), which joinsrninside the same system, and simultaneously, the classicrnfunctions of tracking and surveillance, and all thernfunctions related to the communication, countermeasures,rnand calibration. All these functions constitute the tasks tornexecute. The task scheduler is a key element of the radar,rnsince it realizes the planning and distribution of thernenergy and time resources to be shared and used by allrnthose tasks.rnThis paper presents schedulers based on the use ofrntask queues. Multiple schedulers have been designed andrnstudied, and it has been realized a comparative analysis ofrnthe different performed schedulers. A specific softwarerntool has been designed and developed to perform thernradar system, and to do all the experiments. Anrnappropriate set of radar characteristics has been selectedrnto evaluate the kindness of the task scheduler working.
