acoustic passive location的用法和样例：
- acoustic passive location array with four sensors
- Passive location is an important aspect in acoustical surveillance.In order to locate low altitude targets, the method of acoustic passive location with two arrays based on data fusion was presented.
- Aiming at improving the precision of acoustic passive localization by small size array, we first derived eqs. 1 through 3 to describe the relation between time delay and target location.
