Abstract
A radar apparatus detects objects in a vicinity of a host vehicle on which the radar apparatus is mounted. The radar apparatus includes a microcomputer configured to operate as a prediction processor that calculates a prediction position of a previously detected target in a current detection cycle and an extrapolation processor that executes an extrapolation to determine that a same target as the previously detected target exists in the prediction position for the current detection cycle. The extrapolation processor executes the extrapolation when the prediction position is outside a detection range of the radar apparatus and a speed of the host vehicle is lower than a predetermined value.
Claims10
A radar apparatus that detects objects in a vicinity of a host vehicle on which the radar apparatus is mounted, the radar apparatus comprising a microcomputer configured to operate as:
- a prediction processor that calculates a prediction position of a previously detected target in a current detection cycle;
- and
- an extrapolation processor that executes an extrapolation to determine that a same target as the previously detected target exists in the prediction position for the current detection cycle, wherein
- the extrapolation processor executes the extrapolation when the prediction position is outside a detection range of the radar apparatus and a speed of the host vehicle is lower than a predetermined value.
A signal processing method executed by a microcomputer of a radar apparatus that detects objects in a vicinity of a host vehicle on which the radar apparatus is mounted, the method comprising the steps of:
- (a) calculating, by the microcomputer, a prediction position of a previously detected target in a current detection cycle;
- and
- (b) executing, by the microcomputer, an extrapolation to determine that a same target as the previously detected target exists in the prediction position for the current detection cycle, wherein
- the step (b) executes the extrapolation when the prediction position is outside a detection range of a radar apparatus and a speed of the host vehicle is lower than a predetermined value.
