Abstract:
1. A signal processing device, comprising: an echo signal input module configured to input echo signals from an antenna discharging electromagnetic waves to a predetermined area and to receive the echo signals reflected on a target object; an echo signal level detection module configured to detect a level of each of the echo signals from each location within the predetermined area; a target object detection module configured to detect the target object based on the levels of the echo signals and to output the target object signal levels; a correlation processing module configured to perform scan-to-scan correlation processing of a plurality of scans and to output processed levels of the echo signals based on the levels of the echo signals; and a level adjustment module configured to adjust the processed levels of the echo signals on the basis of at least one of the target object signal levels corresponding to the location of the target object, and to adjust the processed levels of the echo signals at a location outside the location where the target object detection module detects the target object.
