1. A signal processor for processing target echo signal, comprising:
- a filter configured to generate a filtered echo signal by extracting echo signal components within a predetermined frequency band from the target echo signal;
a high resolution signal generator configured to generate a high resolution signal based on the target echo signal, the high resolution signal having higher resolution than the filtered echo signal; and
a synthesizing module configured to synthesize the filtered echo signal with the high resolution signal.

Abstract
A signal processor for processing target echo signal is provided. The signal processor includes a filter configured to generate a filtered echo signal by extracting echo signal components within a predetermined frequency band from the target echo signal, a high resolution signal generator configured to generate a high resolution signal based on the target echo signal, and a synthesizing module configured to synthesize the filtered echo signal with the high resolution signal. The high resolution signal has higher resolution than the filtered echo signal.

15. Computer readable media configured to store a computer executable program in a non-transitory manner, which upon execution by a processor of a computer causes the computer to process target echo signal, comprising:
-
causing a computer to generate a filtered echo signal by extracting echo signal components within a predetermined frequency band from the target echo signal; causing a computer to generate a high resolution signal based on the target echo signal, the high resolution signal having higher resolution than the filtered echo signal; and causing a computer to synthesize the filtered echo signal with the high resolution signal.
