Abstract
There is provided a radar device. A transmitting unit transmits a transmitted wave of a modulation wave whose frequency changes cyclically. A receiving unit receives a reflected wave which is the transmitted wave reflected by a target. A detection unit detects the target based on the reflected wave received by the receiving unit. An adjusting unit adjusts a modulation waveform of the transmitted wave transmitted from the transmitting unit such that the target provided at a known position as an object is detected by the detection unit at the known position and the target is not detected at positions other than the known position by the detection unit.

A radar device comprising:
- a transmitting unit which transmits a transmitted wave of a modulation wave whose frequency changes cyclically;
- a receiving unit which receives a reflected wave which is the transmitted wave reflected by a target;
- a detection unit which detects the target based on the reflected wave received by the receiving unit;
- and
- an adjusting unit which adjusts a modulation waveform of the transmitted wave transmitted from the transmitting unit such that the target provided at a known position as an object is detected by the detection unit at the known position and the target is not detected at positions other than the known position by the detection unit.
A radar device comprising:
- a transmitting unit which transmits a transmitted wave of a modulation wave whose frequency changes cyclically;
- a receiving unit which receives a reflected wave which is the transmitted wave reflected by a target;
- a detection unit which detects the target based on the reflected wave received by the receiving unit;
- and
- an adjustment unit which generates the reflected wave which is supposed to arrive at the receiving unit by the transmitting unit when the target is present at a known position, inputs the received wave from the transmitting unit to the receiving unit, and adjusts the modulation waveform of the transmitted wave transmitted from the transmitting unit such that the target is detected at the known position and is not detected at positions other than the known position by the detection unit.
An adjusting method of a radar device comprising:
- transmitting a transmitted wave of a modulation wave whose frequency changes cyclically;
- receiving a reflected wave which is the transmitted wave reflected by a target;
- detecting the target based on the reflected wave received in the receiving;
- and
- adjusting a modulation waveform of the transmitted wave transmitted in the transmitting such that the target is detected at the known position by the detection unit and is not detected at positions other than the known position when the target as an object is present at a known position.
