The Study of Orientation System by the Technique of Passive
Acoustic Detecting
Abstract
With more and more widely used of the Orientation System, the technique of passive
acoustic detecting has been the important developmental direction. Based on the study of two
key technique , array orientation and time delay detecting ,this paper mainly sets up the
software part for data processing and the hardware part for data transmission, which mainly
includes the wireless transmission module.
Firstly the development of the passive acoustic detecting system and the study status in quo
in the world are discussed. And by discussing the need of passive acoustic detecting study,
this paper introduces the theory knowledge about the system of passive acoustic detecting.
Next the two key technique, array orientation and time delay detecting , are particularly studied,
and a pinpoint math model is calculated, programmed and validated. By validating the
arithmetic, the result of math model arithmetic is accurate and the math model has good
universality. In addition, by discussing all kinds of time delay arithmetic, correlative
arithmetic programs has been compiled and ameliorated. That makes the programs
