To establish the uniform friend or foe situation map, the gridlock is carried out, which converts the positions of platforms and targets into a unified coordinate system. Aiming at the problem of gridlock for the beyond-visual-range platforms on the sea, the beyond-visual-range gridlock methods for offshore platforms and aerial platforms are studied, and the mathematical model of gridlock is founded...
The extend kalman filter theory is studied thoroughly. The model of extend kalman filter is proposed. Three-dimensional extended Kalman filter fusion algorithm is derived based on the information from transmission stations and receiving stations of bistatic sonar system. As the bigger error of it in z direction, an improved three-dimensional extended Kalman filter fusion algorithm with measurements...
To solve data alignment problem of multi-platform multi-sensor on the sea, a multi-sensor data alignment method based on relative bearing and range is proposed. Using the measurements of relative bearing and range among the maritime platforms, the targets' positions measured are transformed in the sensor relative bearing cordinates of a platform, and the sensor alignment is achieved. The method above...
In this paper, the authors present a new method of HRR profile formation based on the LFM signal fusion of the multiple radars with multiple frequency bands. The principle of the multiple radars signal fusion improving the range resolution is analyzed. During the fusion process, the B-splines interpolation and an entropy-minimization principle based phase compensation algorithm are applied. The theoretical...
