1. A display 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;an extracting module for extracting the reception signal for each identified target kind;a layer storage that stores the extracted reception signals such that each extracted 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 selector for selecting at least one layer for display; anda display processorfor generating an individual radar image for each of the selected at least one layer such that each generated individual radar image corresponds to an identified target kind, andfor displaying the generated individual radar image corresponding to the selected at least one layer. 2. The display device of claim 1, wherein the identifying module identifies at least any one of the target kinds associated with the reception signal, the target kinds including a land, a ship, a buoy, a flag buoy, a sea surface reflection, a rain-and-snow clutter, and a white noise. 3. The display device of claim 1, further comprising a map information acquiring module for acquiring map information; wherein the identifying module identifies the target kind of the reception signal based on the map information. 4. The display device of claims 1, further comprising an AIS information acquiring module for acquiring AIS information; wherein the identifying module identifies the target kind of the reception signal based on the AIS information. 5. The display device of claims 1, wherein the identifying module identifies the reception signal indicating a sea surface reflection target kind. 6. The display device of claims 1, wherein the identifying module identifies the reception signal indicating a rain-and-snow clutter target kind. 7. The display device of claim 1, the display processor synthesizing each generated individual radar image corresponding to each selected layer to generate a displayed radar image based on the synthesized individual radar images. 8. The display device of claim 1, displaying the generated individual radar image comprising: performing individual image processing for each generated individual radar image corresponding to a selected layer based on the target kind of the selected layer, the individual image processing including enhancing or suppressing or adjusting one or more of a transparency and a color tone of the individual radar image based on the target kind of the selected layer. 9. The display device of claim 8, performing individual image processing for each generated individual radar image including suppressing the individual radar image associated with a rain-and-snow clutter target kind or a white noise target kind or a sea surface reflection target kind. 10. The display device of claim 8, performing individual image processing for each generated individual radar image including enhancing the individual radar image associated with a ship target kind or a land target kind. 11. The display device of claim 5, further comprising: a kind-based signal processor for performing sea surface reflection signal processing for an extracted reception signal identified as a sea surface reflection target kind, said sea surface reflection signal processing being different from signal processing for other target kinds. 12. The display device of claim 6, further comprising: a kind-based signal processor for performing rain-and-snow clutter signal processing for an extracted reception signal identified as a rain-and-snow clutter target kind, said rain-and-snow clutter signal processing being different from signal processing for other target kinds. 13. The display device of claim 1, where: the display layer selector selects at least two layers for display; andthe display processor generates an individual radar image for each of the selected at least two layers such that each generated individual radar image corresponds to an identified target kind. 14. A method, comprising: acquiring reception signals received by a radar antenna during a single antenna scan;identifying a target kind of each acquired reception signal;extracting the reception signal for each identified target kind;storing the extracted reception signals in a storage such that each extracted reception signal is associated with a layer according to the identified target kind, each layer being associated with a particular target kind;selecting at least one stored layer for display;generating an individual radar image for each of the selected at least one layer such that each generated individual radar image corresponds to an identified target kind, anddisplaying the generated individual radar image corresponding to the selected at least one layer. 15. The method of claim 14, the method further comprising: performing a kind-based signal processing for an extracted reception signal based on the target kind, said kind-based signal processing being different from signal processing for other target kinds. 16. The method of claim 14, the method further comprising: synthesizing each generated individual radar image corresponding to each selected layer to generate a displayed radar image based on the synthesized individual radar images. 17. The method of claim 14, displaying the generated individual radar images comprising: performing individual image processing for each generated individual radar image corresponding to a selected layer based on the target kind of the selected layer, the step of performing individual image processing including enhancing or suppressing or adjusting one or more of a transparency and a color tone of the individual radar image based on the target kind of the selected layer. 18. The method of claim 17, performing individual image processing for each generated individual radar image including suppressing the individual radar image associated with a rain-and-snow clutter target kind or a white noise target kind or a sea surface reflection target kind. 19. The method of claim 17, performing individual image processing for each generated individual radar image including enhancing the individual radar image associated with a ship target kind or a land target kind. 20. The method of claim 14, said selecting including selecting at least two layers for display; and generating an individual radar image including generating an individual radar image for each of the selected at least two layers such that each generated individual radar image corresponds to an identified target kind. 21. The method of claim 17, where each of the steps of enhancing, suppressing, and adjusting one or more of a transparency and a color tone of the individual radar image are performed based on an indication of importance associated with the selected layer.
