Description

Technical field [0001] The invention relates to an underwater target track measurement and processing system. Background technique [0002] To increase the operating distance of underwater acoustic measuring equipment, the only way to increase the signal-to-noise ratio of the receiver is to increase the signal-to-noise ratio of the receiver under certain signal energy conditions. At present, there are many technologies in this area, such as related technologies, LMS adaptive linear accumulation technology, ALE line spectrum related technologies, etc., but these technologies are more suitable for pulse signal processing above 10MS, and have little benefit for pulse signals below 2MS, and measurement errors Also larger. [0003] A phase-locked tracking processor appears in the prior art. This processor has superior performance, simple structure, and is easy to be made into an ultra-small circuit board. The application of this processor can make the performance of the existing equipm...
