Method for characterizing mode s question and response density and secondary radar implementing such method

摘要

The density of mode s questions and responses in the environment covered by the secondary radar is as followsFirst step, the radar isThe mode s target is detected by its synchronous response to the question transmitted by the radar and identifying its position- detect an asynchronous response that is transmitted by the mode s target and is not induced by the radar (32)For each target, associate the asynchronous response to its synchronous response to the radarFirst step to doThe second step is the radarBased on the above Association, the response speed of each target is determined by counting the number of synchronous and asynchronous responses received from the target for a given period of time (35);Determining the response speed per cell by counting the number of synchronous and asynchronous responses received by each target in each cell divided by the environment into the basic space cell It is characterized by a second step of performing judgment (36, 37).Diagram
