<p>An interrogation transmission method of a secondary surveillance radar compares prediction angle ranges of transmissions of interrogations with an antenna beam-width (S1, S2), and transmits the interrogations at every roll-call period if the prediction angle ranges of the interrogations are narrower than the antenna beam-width (S3). In contrast, if the prediction angle ranges of the interrogations are wider than the antenna beam-width, the radar respectively sets a period to transmit the interrogations and a period not to transmit the interrogatio</p> |
