Abstract
Official abstract text for this publication.
There is provided a radar apparatus configured to emit a transmission wave, to receive a reflected wave as a reception signal, and to derive target information including at least position information of a target from peak signals which are extracted by performing FFT processing for a beat signal that is generated from the reception signal. A determination unit is configured to determine whether a specific peak signal exists at a frequency that is distant from a frequency of the peak signal existing at a first frequency by a frequency of one selected peak signal selected from the plurality of peak signals. An exclusion unit is configured to exclude the target information corresponding to the selected peak signal from an output object of the radar apparatus when the specific peak signal exists.
First claim
Opening claim text (preview).
What is claimed is: 1. A radar apparatus configured to emit a transmission wave relating to a transmission signal to be frequency-modulated, to receive a reflected wave coming from a target at which the transmission wave is reflected as a reception signal, and to derive target information including at least position information of the target from peak signals which are extracted by performing FFT processing for a beat signal that is generated from the reception signal, the radar ap…
