Abstract
There is provided a radar device. A transmitting unit transmits a transmitted wave based on a transmitted signal which is frequency modulated. A receiving unit acquires a received signal based on a reflected wave which is the transmitted wave reflected by a target. An instruction unit matches a predetermined timing at which a frequency of the transmitted signal becomes a predetermined frequency to an output timing at which a beat signal based on the transmitted signal and the received signal is output from the receiving unit and outputs the beat signal from the receiving unit.
Claims14
A radar device comprising:
- a transmitting unit which transmits a transmitted wave based on a transmitted signal which is frequency modulated;
- a receiving unit which acquires a received signal based on a reflected wave which is the transmitted wave reflected by a target;
- and
- an instruction unit which matches a predetermined timing at which a frequency of the transmitted signal becomes a predetermined frequency to an output timing at which a beat signal based on the transmitted signal and the received signal is output from the receiving unit and outputs the beat signal from the receiving unit.
A radar device comprising:
- a transmitting unit which transmits a transmitted wave based on a transmitted signal which is frequency modulated;
- a receiving unit which acquires a received signal based on a reflected wave which is the transmitted wave reflected by a target;
- and
- an instruction unit which synchronizes a timing at which a frequency of the transmitted signal is lowered by modulation with a timing at which the received signal is A/D converted.
A control method of a radar device comprising:
- transmitting a transmitted wave based on a transmitted signal which is frequency modulated;
- acquiring a received signal based on a reflected wave which is the transmitted wave reflected by a target;
- and
- outputting a beat signal so as to match a predetermined timing at which a frequency of the transmitted signal becomes a predetermined frequency with an output timing at which the beat signal based on the transmitted signal and the received signal is output by the acquiring.
A control method of a radar device, comprising:
- transmitting a transmitted wave based on a transmitted signal which is frequency modulated;
- acquiring a received signal based on a reflected wave which is the transmitted wave reflected by a target;
- and
- synchronizing a timing at which a frequency of the transmitted signal is lowered by modulation with a timing at which the received signal is A/D converted.
