<p>PROBLEM TO BE SOLVED: To provide an airport plane radar surveillance device reducing the surveillance load of an observer and facilitating quick and exact judgment by preventing the deviation on indication from a runway or guideway of airplane and suppressing the difference of actual direction of the airplane from indicated direction of the airplane without damaging original optimum tracking processing. SOLUTION: Path for moving of airplanes on airport plane is definite to a certain degree, which is set as planned moving path. A tracking processor 86 performs a uniform smoothing process as a conventional case, however; indication smoothing processor 100 performs smoothing processing for indication weighted along the planned moving path. By this smoothing processing for indication, surer vector marker of the airplane with less effect of noise and the like of input data than the case uniformly processed is indicated on an indication part 94.</p> |
