A detecting system includes a tag, a radar device that transmits transmission radio waves to the tag and acquires reception radio waves produced by the transmission radio waves being reflected by the tag, and a detecting apparatus. The tag includes a pattern made of a plurality of materials that reflect or scatter radio waves received from the radar device, and the pattern includes a known pattern known to the detecting apparatus and an unknown pattern unknown to the detecting apparatus. The detecting apparatus includes a specifying unit that calculates a relative velocity between the radar device and the tag, with which the known pattern can be detected from the reception radio waves, and specifies a condition for the radar device to transmit transmission radio waves for estimating the unknown pattern, from the calculated relative velocity, and a notification unit that notifies the radar device of the specified condition.
