Problems solved by technology

Therefore, this kind of method has defects in principle, and the measurement accuracy is affected.
[0019] 2. Not suitable for offshore surveys;
[0020] For example, in US Patent No.6545945, signals of different frequencies are transmitted, and the relationship between sediment sound attenuation and frequency is quite time-consuming, and it is only suitable for indoor measurement, not for offshore measurement.

Embodiment Construction

[0071] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0072] Such as figure 1 As shown, when the shallow formation profiler of the present invention is used to measure the physical properties of seabed sediments, it is installed on a carrier 100 , for example, a ship can be used as the carrier 100 . The shallow formation profiler generally includes a wet end 200 and a dry end 600, which are connected by cables. The wet end 200 includes a transducer array 300 , an electronic extension 400 and a temperature sensor 500 , and the wet end 200 is usually below the water surface 103 ; the dry end 600 includes a terminal computer 601 , which are usually installed above the water surface 103 . The shallow formation profiler transmits a conical beam 101 into the water through the transducer array 300, and receives the reflected signal of the seabed sediment 102, and after processing by the electr...

Abstract

Carrying out straight line fit between instantaneous frequency point corresponding to peak point of envelope signal of echo signals and adjacent instantaneous frequency points, the method obtains relation between accoustic attenuation of marine bottom sediment and frequency. The system includes transducer array, electronic extension, temperature sensors, and main end in use for monitor and control, and storage. The designed electronic extension carries out data process by using the method provided by the invention. Featureas are: overcoming current technical shortcomings in principle, correct philosophy of measurement, quick measurement and accurate result.

Description

technical field [0001] The present invention relates to a method and system for measuring the characteristics of seabed sediments, more specifically, to a method and system for measuring the physical characteristics of seabed sediments with a shallow formation profiler. Background technique [0002] With the development of marine science and ocean development, people are more and more eager to understand the physical properties of seabed sediments. There are two types of acoustic methods for measuring seafloor sediments: one is telemetry at sea using acoustic methods; the other is sampling seafloor sediments and measuring them acoustically in a laboratory. Both methods have advantages and disadvantages. Because the sediments on the seabed are very complex, the main direction of various acoustic measurement methods is to adopt correct principles, analyze errors in depth, and improve the reliability of various acoustic measurement methods. [0003] 1999 U.S. Patent No. 5,991...
