Signal processing device, radar device, signal processing program, and signal processing method

Abstract

The radar system includes a target detection unit (701) that detects a detection point resulting from a mirror ghost of the target based on the reflected waves of the radio waves transmitted by the radar unit that are reflected by the target and received by the radar unit, and calculates the distance and direction of the detection point from the radar unit; a target candidate point calculation unit (703) that calculates target candidate points by estimating the propagation path of the radio waves based on the distance and direction calculated by the target detection unit (701) and information indicating structures present in the vicinity of the aircraft; a combination detection unit (704) that detects a combination of target candidate points based on the target candidate points calculated by the target candidate point calculation unit (703); and a movement direction and speed estimation unit (705) that estimates the movement direction and speed of the target based on the speed of the detection point detected by the target detection unit (701) and the combination of target candidate points detected by the combination detection unit (704).
