1. A bottom detection method used in the multibeam bathymeter sonar is introduced. The method is based on the separate aperture method, which is associated with phase information.

2. Multi-beam swath bathymeter is a seafloor mapping equipment with high efficiency, high accuracy and excellent resolution, especially fitted for wide sweep mapping.

3. In the paper, the miniaturization of multi-beam swath bathymeter based on the H/HCS-017, the first multi-beam swath bathymeter of our country, was argued.

4. Multi-beam Swath Bathymeter is a kind of newly developed advanced seafloor surveying equipment with high efficiency, high accuracy and fine terrain resolution.

5. While working on the sea, the multibeam bathymeter is requested more strictly to the path of the ship and this doubtless request the precision of ship sail path.

6. It can used to improve and consummate the miniaturization of multi-beam swath bathymeter further.

6. try its best to collect and create good sentences.

7. Estimation of dynamic error is an imperfect solved problem, for the multi-beam swath bathymeter developed in recent years.

8. In the 1990s, Harbin Engineering University Underwater Acoustics Academe had developed H/HCS-017 Multibeam Swath Bathymeter for navy.

9. In the paper, the main works are exploiting a set of signal processing system for shallow multi-beam swath bathymeter.

10. The multi-beam swath bathymetric technique needs more improvement with the developing of modern science and technology. Miniaturization of the bathymeter is currently the main goal of this field.

11. The paper has laid the foundation for the further development of shallow multi-beam swath bathymeter in job.
