Transponder landing system

The based on ground source machine of landing system, providing precise CATI and a landing navigation. Is air mapping differential horizontal support phase for arrival time ATCRBS responder piece, a airplane's height of. The replied matched is composed of displaying multiple detector of the antenna, is transmitted to the detector, and is demodulated and digitally. The data is transmitted to the central processor for calibrations and multi-channel tube. Is an is related of the differential phase jumping of single detecting measuring), the diversity antenna processor transformations and has matched multi-channel of capers and colour noise isolation airplane responder. Diversity antenna the estimating distance is maintained a Kalman filter processing; The distance of estimating is used for aircraft adjusting the height difference phase connected data. Phase and measuring apparatus for arrival time of measuring head is a Kalman filter processing, so reaches the aircraft pointing high accuracy of electric. For similar and a phase and arrival time, subsystem for measurement of azimuth of the aircraft. And and angle of the number of the combination the azimuth and height of airplane and it; and a groove aircraft the error information of airplane is opposite to a.
