Information processing apparatus, system, method and storage medium

A method executed by an information processing apparatus, comprising:

• acquiring a first observation signal from a radar device with a plurality of antennas configured to transmit a radar signal and to receive a radar echo based on a reflected wave of the radar signal, the first observation signal being based on the radar signal and the radar echo;
• generating a first radar image by executing a signal process based on a predetermined first condition, with respect to the first observation signal;
• and
• generating a second radar image by executing a signal process based on a second condition which is different from the first condition, with respect to the first observation signal, wherein
• the first and second radar images are used as training data for a learning model to detect an object to which the radar signal is transmitted.

A non-transitory computer-readable storage medium having stored thereon a program which is executed by a computer, the program comprising instructions capable of causing the computer to execute functions of:

• acquiring a first observation signal from a radar device with a plurality of antennas configured to transmit a radar signal and to receive a radar echo based on a reflected wave of the radar signal, the first observation signal being based on the radar signal and the radar echo;
• generating a first radar image by executing a signal process based on a predetermined first condition, with respect to the first observation signal;
• and
• generating a second radar image by executing a signal process based on a second condition which is different from the first condition, with respect to the first observation signal, wherein
• the first and second radar images are used as training data for a learning model to detect an object to which the radar signal is transmitted.
