1. A method for detecting targets using radar, comprising:
generating a map of an environment of the radar in real time;
calculating a probability of a presence of false targets in multiple regions of the environment of the radar based on said map of the environment of the radar;
receiving digital data transmitted by the radar corresponding to at least one radar target, comprising digital data on a location of the at least one radar target; and
calculating a reliable confidence index associated with the at least one radar target based on a probability of the presence of false targets in a region where the at least one radar target is located, wherein
the digital data transmitted by the radar corresponding to the at least one radar target comprise an initial confidence index, and
the calculating the reliable confidence index associated with the at least one radar target is based on the initial confidence index and a complement of the probability of the presence of false targets in the region where the at least one radar target is located.
