Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a radio wave sensor and a detection method that can detect an object with high sensitivity.SOLUTION: A radio wave sensor includes: a transmission unit for transmitting a pulse radio wave indicating a pre-distorted signal based on a code sequence to a target area; a reception unit for receiving a radio wave from the target area; a calculation unit for calculating correlation between data indicated by the radio wave received by the reception unit and the code sequence; and a detection unit for detecting a target in the target area on the basis of the correlation calculated by the calculation unit. The pre-distorted signal is a signal created on the basis of a transmission characteristic within the radio wave sensor calculated based on the data in the case of a radio wave for adjustment being transmitted from the transmission unit and the code sequence.SELECTED DRAWING: Figure 13
【課題】対象物を感度良く検出することが可能な電波センサおよび検知方法を提供する。【解決手段】電波センサは、符号系列に基づく予歪信号を示すパルス状の電波を対象エリアへ送信する送信部と、前記対象エリアから電波を受信する受信部と、前記受信部によって受信された電波の示すデータと前記符号系列との相関を算出する算出部と、前記算出部によって算出された前記相関に基づいて、前記対象エリアにおける対象物を検出する検出部とを備え、前記予歪信号は、調整用の電波を前記送信部から送信した場合における前記データに基づいて算出された前記電波センサ内の伝送特性、および前記符号系列に基づいて作成された信号である。【選択図】図13 |
