Abstract
[Object] To provide a signal processing device capable of distinguishing and measuring a plurality of measurement targets even with simple configuration. [Solution] Provided is a signal processing device including: a reception processing unit configured to receive a response to a predetermined signal transmitted from a transmission antenna; and a determination unit configured to determine the plurality of measurement targets by a response to a plurality of signals corresponding to a second direction having a predetermined range different from a first direction having a predetermined range.
Claims15
A signal processing device comprising:
- a reception processing unit configured to receive a response to a predetermined signal transmitted from a transmission antenna;
- and
- a determination unit configured to determine the plurality of measurement targets by a response to a plurality of signals corresponding to a second direction having a predetermined range different from a first direction having a predetermined range.
A radar system comprising:
- a transmission antenna configured to output a predetermined signal;
- a reception antenna configured to receive a response to the predetermined signal transmitted from the transmission antenna;
- and
- a determination unit configured to determine the plurality of measurement targets by a response to a plurality of signals corresponding to a second direction having a predetermined range different from a first direction having a predetermined range.
The radar system according to claim 11,
- wherein the determination unit, in a case where a plurality of measurement targets fails to be determined by the response of a time group earlier in a time direction, determines the plurality of measurement targets by the response of a time group later in the time direction.
A signal processing method comprising:
- receiving a response to a predetermined signal transmitted from a transmission antenna;
- and
- determining the plurality of measurement targets by a response to a plurality of signals corresponding to a second direction having a predetermined range different from a first direction having a predetermined range.
