Radar system and detection method

摘要

A radar system includes an arithmetic processing unit, which sends a warning command to a warning device when a local minimum point of the intensity of the reflected wave from a target within a predetermined detection range is detected. By determining whether it is necessary to send a warning command based on whether there is a local minimum point of the intensity within the detection range, it is made possible to determine whether it is necessary to send a warning command more quickly as compared to the conventional system.

1. A radar system for a vehicle, which is for determining a height of a target, comprising:
an oscillator that is configured to oscillate to generate a transmitted wave; a transmitting antenna that is configured to output the transmitted wave; a receiving antenna that is configured to receive a reflected wave from the target; and an arithmetic processing unit that is configured to calculate an intensity of the reflected wave and to determine a relative distance to the target, wherein the arithmetic processing unit is configured to detect whether a curve of the intensity of the reflected wave associated with the relative distance has a local minimum point within a detection range of the relative distance to the target, wherein the detection range is set in the arithmetic processing unit in advance, and the arithmetic processing unit is configured to determine the height of the target based on a value of the relative distance corresponding to the local minimum point of the intensity within the detection range, with reference to an association between (i) the intensity, (ii) a relative distance between the vehicle and the target, and (iii) the height of the target.
