摘要

PROBLEM TO BE SOLVED: To suppress the reduction of use efficiency of beam schedule in a mode S secondary surveillance radar and improve the accuracy and reliability of monitoring an aircraft.;SOLUTION: When a mode S individual response signal is not obtained from an aircraft to be monitored and it becomes impossible to continue monitoring by the mode S individual response signal, a monitoring processing section 133 uses the positional information on the aircraft included in a mode S extension squitter transmitted from the aircraft to be monitored, so as to compute the predicted position of the aircraft in the following scanning and the predicted range according thereto, and a channel managing section 134 performs scheduling of mode S individual question response according to the predicted range that is computed by using the mode S extension squitter in the monitoring processing section 133.;COPYRIGHT: (C)2011,JPO&INPIT
