Learning device, learning method, recording medium, and radar device

A method comprising:

• acquiring, by a learning device, a reception signal of a predetermined beam specification based on a received wave and a tracking signal generated based on the reception signal from a radar device, wherein
• the reception signal is a processed signal after demodulation processing and coherent integration processing in the radar device,
• the reception signal is generated by applying, to the processed signal, inverse coherent integration processing that is an inverse processing of the coherent integration processing and modulation processing that is an inverse processing of the demodulation processing using a beam specification different from the processed signal;
• generating, by the learning device, learning data using the reception signal and the tracking signal;
• learning, by the learning device, a new target detection model for detecting a target from the reception signal, using the learning data, wherein
• the new target detection model differs from an old target detection model for detecting the target from the reception signal,
• generating, by a transceiver of the radar device, a transmission signal based on a transmission wave specification;
• amplifying, by an antenna unit of the radar device, the generated transmission signal;
• emitting, by the antenna unit, a transmission wave in a provided direction;
• performing, by a first control/data processing unit of the radar device, processing using the old target detection model for detecting the target;
• performing, by a second control/data processing unit of the radar device, processing using the new target detection model for detecting the target from the reception signal;
• and
• integrating, by an integration unit of the radar device, processing results of the first and second control/data processing units to generate the transmission wave specification on which basis the transceiver generates the transmission signal and to generate the provided direction in which the antenna unit emits the transmission wave,
• wherein integration of the processing results of the first and second control/data processing units reduces operation fluctuation of the radar device as a result of the new target detection model.
