摘要：
The passive location method based on angle measurement is studied, the low positioning accuracy and Geometric Dilution of Precision (GDOP) on some target azimuth of dual-station angle measurement location system are founded. Based on the structural characteristics of the airborne platform, an infrared passive angle measurement location method for the single plane is presented. According to the orthogonal method, four measuring stations are loaded onto the airborne platform, they are composed of two orthogonal angle measurement location systems. By choosing the location information of the two systems properly, the GDOP problem can be overcome effectively. Finally, the simulation results show that the method can effectively overcome the GDOP problem and improve the positioning accuracy. (C) 2017 Elsevier B.V. All rights reserved.
