METHOD OF CHARACTERIZING THE DENSITY OF MODE S INTERROGATIONS AND RESPONSES AND SECONDARY RADAR IMPLEMENTING SUCH A PROCEDURE

摘要

The density of Mode S interrogations and responses in the environment covered by a secondary radar is characterized according to the following steps: a first step in which said radar performs: ○ the detection and location of Mode S targets by means of their responses synchronous with the interrogations emitted by said radar; ○ the detection (32) of the asynchronous responses emitted by the Mode S targets, unsolicited by said radar; ○ for each target, the association (33) of its asynchronous responses with its synchronous response to said radar; - a second step in which said radar performs: ○ from said association, the determination (35) of the response rate of each target by counting the number of synchronous and asynchronous responses received from said target per given period of time; ○ said environment being divided into elementary space cells, the determination (36, 37) of the response rate per cell by counting the number of synchronous and asynchronous responses received by each target in each cell, said rate characterizing the density of interrogations Mode S per cell.
