Example Embodiment

[0028] The present invention will be further explained in detail with reference to the drawings.

[0029] On the basis of the collected target mobile phone signal, the invention introduces the probability calculation of the pseudo target position to locate the target.

[0030] The mobile phone positioning algorithm of the present invention obtains the energy size and direction of the target mobile phone based on four orthogonal direction antennas, and obtains the position of the energy collection point when the energy is collected based on GPS. The algorithm is divided into the following steps:

[0031] 1. Determine the target location area

[0032] The position information obtained by GPS is the longitude and latitude. The longitude and latitude can correspond to the position on the earth's surface, and the plane position of the collected energy can be determined. When calculating the target location, first determine in which area to calculate the target location. The determination ...

Abstract

The invention discloses a mobile phone positioning algorithm based on mobile phone signal direction and strength. The algorithm comprises the following steps: a target position area is determined, based on energy collection point positions acquired by GPS, each energy collection point presents as a <longitude, latitude> value pair, a base point of the target area is obtained through taking the even, and the base point extends certain distance for four directions including east, west, north and south to serve as a target calculation area; a 90 degrees included angle area is determined, the area is considered as an area and direction where a target most possibly falls in, and a precision direction of the target is further determined; a target located area is determined according to the acquired signal strength; target position probabilities are calculated, probabilities of all points are sorted, and the greater probability of a false target is, the greater possibility of a true target is. According to the invention, the positioning precision is improved, as with the collected signal energy is increased, the range of true target is narrowed, and the target is positioned in a position near one false target point.

Description

technical field [0001] The invention belongs to mobile terminal positioning technology in the field of wireless communication, in particular to a mobile phone positioning algorithm based on the direction and strength of mobile phone signals. Background technique [0002] Mobile phone positioning is divided into active positioning and passive positioning. Active positioning means that mobile phone users locate their own location through the software and hardware of the mobile phone they hold; passive positioning refers to obtaining the location of other people's mobile phones through auxiliary equipment such as base station information or mobile phone signals. The present invention belongs to passive positioning. The existing passive positioning mainly improves the positioning accuracy by improving the performance of hardware devices and optimizing the processing of mobile phone signals. [0003] The shortcomings of existing technologies are mainly reflected in three aspect...
