Post subject: ugg prezzo Top empty axis tilt blind carrier track
Top empty axis tilt blind carrier tracking radar study
. . Period of 7s; the sampling period is D = 0.01s. Target level of the earth coordinate system, azimuth 45, elevation angle is 85. , Cross-axis tilt deck of 30. Fixed angle. For comparison purposes, also calculated the orthogonal axis of radar wave in the vessel E ? E Wang pregnancy a) t cross-axis of the tilt angle rb) i-axis tilt angle of Figure 8, two-axis tilt system, tilt Fig8Thrc ~ a 0XeF, pitchingang [c case of tilt can be seen from the simulation results, tilt axis tracking radar system in the headspace goals, the pitch angle than the orthogonal axis of the pitch angle is small, and less than 90. To reduce the small level of the pitch axis is not strictly caused by the orientation error. Harbin Engineering University 6 Conclusions theoretical calculations and simulation results show that the radar system of the tilt axis cross-axis and the deck surface to carry out an angle to the airspace in the whole range, in engineering applications. At a higher angle tracking accuracy. And has the following advantages: (1) the elimination of the ship rocking and rolling due to beam tilt (21 to overcome the vertical shaft is not strictly between the headspace caused the error area too, can over the top and sea-skimming target goals Tracking results have been verified in simulation.
