Single receiving machine location method based on signal detection probability and wave angle estimation

Provided is a single receiving machine location method based on detection probability and wave angle estimation. Only receiving data of one receiving machine are required to estimate distance and angle simultaneously. The method is divided into three portions. The first portion includes calculating distance between the receiving machine and a target user by estimating the detection probability of the target user and building relation between the detection probability and the distance. The first portion achieves algorithm of a radio network to the target user and based on distance measurement and reduces algorithm complexity. The second portion includes utilizing the multiple signal classification algorithm to calculate wave angle of a target user signal source to obtain an included angle between the target user and the receiving machine. The third portion combines results of the first portion and the second portion to calculate position coordinate of the target user by simple calculation. Compared with a traditional method, the location method has the two advantages of being low in hardware cost due to the fact that only one receiving machine is required to achieve target user location and simple and easy to carry due to the fact that the detection probability is utilized to calculate distance, thereby greatly reducing system overhead.
