Claim:
1. An echo signal processing device operatively coupled to an antenna and a display unit, the antenna being configured to transceive radio waves, the device comprising: a processor configured to execute a positional information acquiring module, an analytic area specifying module, and a calculating module; and a storage configured to store a plurality of analytic area images, wherein the image generating module, executed on the processor, is configured to generate an echo image at each of a plurality of timings, the echo images generated based on echo signals, each of the echo signals received by the antenna installed in a movable body and configured to transceive a radio wave that causes the echo signal, and the image generating module is configured to cause the display unit to display the echo images; the positional information acquiring module, executed on the processor, is configured to acquire absolute positional information of the movable body; the analytic area specifying module, executed on the processor, is configured to specify an analytic area in each echo image by an absolute position, based on the absolute positional information acquired by the positional information acquiring module; each of the analytic area images is a part of each of the echo images, the part corresponding to the analytic area; and the calculating module, executed on the processor, is configured to calculate echo signal information that is information regarding the echo signals from the analytic area, based on the plurality of analytic area images stored in the storage, and the calculating module is configured to cause the display unit to display the echo signal information.
