Radar system, processing method, and processing program

A processing method in a radar apparatus that is mounted on a vehicle and that transmits a predetermined signal to an outside of the vehicle and receives a predetermined signal from the outside of the vehicle to detect information regarding a target relative to the vehicle,

• the radar apparatus including a first radar apparatus that transmits and receives a signal with a first frequency and has a first detection area and a second radar apparatus that transmits and receives a signal with a second frequency different from the first frequency and has a second detection area different from the first detection area, and
• the first radar apparatus and the second radar apparatus being arranged on the vehicle such that the first detection area and the second detection area partially overlap with each other, comprising:
• a first step of generating, by the second radar apparatus, second information regarding the target relative to the vehicle based on information detected in the second detection area and transmitting the second information to the first radar apparatus;
• and
• a second step of generating, by the first radar apparatus, first information regarding the target relative to the vehicle based on information detected in the first detection area, performing arithmetic integration processing based on the first information and the second information received from the second radar apparatus to generate integrated information, and transmitting the integrated information to a higher-level apparatus.

A processing program used for a radar apparatus that is mounted on a vehicle and that transmits a predetermined signal to an outside of the vehicle and receives a predetermined signal from the outside of the vehicle to detect information regarding a target relative to the vehicle,

• the radar apparatus including a first radar apparatus that transmits and receives a signal with a first frequency and has a first detection area and a second radar apparatus that transmits and receives a signal with a second frequency different from the first frequency and has a second detection area different from the first detection area,
• the first radar apparatus and the second radar apparatus being arranged on the vehicle such that the first detection area and the second detection area partially overlap with each other, and
• the processing program causing a computer to execute
• a first step of generating second information regarding the target relative to the vehicle based on information detected in the second detection area and transmitting the second information to the first radar apparatus, and
• a second step of generating first information regarding the target relative to the vehicle based on information detected in the first detection area, performing arithmetic integration processing based on the first information and the second information received from the second radar apparatus to generate integrated information, and transmitting the integrated information to a higher-level apparatus.
