Abstract
A target determination apparatus for determining type of a target, includes a transmission unit, a reception unit, and a determination unit. The transmission unit emits an electromagnetic wave. The reception unit receives the electromagnetic wave reflected at the target to obtain reception information. The determination unit determines the type of the target on the basis of radar cross section obtained from the reception information.
Claims15
A target determination apparatus for determining type of a target, comprising:
- a transmission unit which emits an electromagnetic wave;
- a reception unit which receives the electromagnetic wave reflected at the target to obtain reception information;
- a first determination unit which determines the type of the target on the basis of a radar cross section of the target obtained from the reception information;
- a mass calculation unit which obtains mass of the target on the basis of the type of the target determined by the first determination unit;
- and
- an energy calculation unit which obtains energy of the target on the basis of the mass of the target obtained by the mass calculation unit.
A target determination apparatus for determining type of a target, comprising:
- a determination unit which determines the type of the target on the basis of radar cross section of the target;
- a first mass calculation unit which obtains mass of the target on the basis of the type of the target determined by the determination unit;
- and
- a first energy calculation unit which obtains energy of the target on the basis of the mass of the target obtained by the first mass calculation unit.
A target judgment apparatus for judging type of a target, comprising:
- a target monitor unit including:
- a transmission unit which emits an electromagnetic wave;
- a reception unit which receives the electromagnetic wave reflected at the target to obtain reception information;
- and
- a radar-cross-section calculation unit which calculates radar cross section of the target on the basis of the reception information;
- a first determination unit which determines the type of the target on the basis of the radar cross section provided by the target monitor unit;
- a second determination unit which determines the type of the target in a different manner from the first determination unit;
- and
- a judgment unit which judges the type of the target on the basis of determination result of the first determination unit and determination result of the second determination unit.
A determination aid apparatus for aiding a target determination apparatus, which determines type of a target, the determination aid apparatus comprising:
- a transmission unit which emits an electromagnetic wave;
- a reception unit which receives the electromagnetic wave reflected at the target to obtain reception information;
- and
- a radar-cross-section calculation unit which obtains a radar cross section of the target on the basis of reception power of the reflected electromagnetic wave received by the reception unit, distance to the target, transmission power of the electromagnetic wave emitted by the transmission unit, wavelength of the electromagnetic wave emitted by the transmission unit, power gain of the transmission unit, and power gain of the reception unit;
- a mass calculation unit which obtains mass of the target on the basis of the type of the target determined by the first determination unit;
- and
- an energy calculation unit which obtains energy of the target on the basis of the mass of the target obtained by the mass calculation unit, wherein:
- the reception power of the reflected electromagnetic wave and the distance to the target are obtained from the reception information.
