Patent ID: 8730090

Claim:
A signal processing device, comprising: a reception signal acquiring module for acquiring reception signals received by a radar antenna during a single antenna scan; an identifying module for identifying a target kind of each reception signal based on a target associated with the reception signal; an extracting module for extracting the reception signal for each identified target kind; and a kind-based signal processing module for performing individual signal processing for each target kind of the extracted reception signal, the individual signal processing including a different signal processing for each target kind; a layer storage module that stores the reception signals such that each signal-processed reception signal is associated with a layer according to the identified target kind, each layer being associated with a particular target kind; a display layer selecting module for selecting two or more of the layers; and a display processing module for generating an individual radar image for each layer such that each generated individual radar image corresponds to an identified target kind and for displaying the generated individual radar images corresponding to the selected layers.
