A system and method for planning radar missions. The system includes a processing unit and a display. The method includes estimating the execution time of a plurality of radar tasks to be executed periodically at respective planned repetition rates, and assessing, using rate monotonic scheduling, whether the tasks can be executed at their respective planned repetition rates. The display may be employed to display a graphical representation of a path to be flown repeatedly by the aircraft, and, superimposed on the displayed path, symbols indicating whether at any point on the path the radar will be able to execute each task at its respective planned repetition rate, and whether each of a plurality of areas to be surveyed by the radar, each corresponding to a respective radar task, is in the field of view pattern of the radar.
