An Algorithm Of The Dpfrc Real-Time Location For The Moving Emmiter By A Moving Singal Observer

The traditional algorithm of single station location are mainly for the single moving station to the fixed emmiter or the fixed station to the moving emmiter,however, it is very difficult for a moving station to bring about a fast and accurate location to the moving emmiter. This paper presents a real-time joint positioning algorithm using four observations,including frequency,azimuth, the rate of phase difference and Doppler frequency. achieves real-time location of the target,and analyzes the GDOP and the main factors which affect the positioning accuracy.
