Method for detecting radars and related device

A method for detecting at least one radar in an environment, the method being implemented by a device including a calculating unit and an antenna array including at least one antenna adapted to make acquisitions of the environment as acquisition signals and to receive and transmit the acquisition signals in a digital form to the calculating unit, the calculating unit being adapted to make processing on digitised signals, the method comprising:

• receiving and digitising the acquisition signals as digitised signals and transmitting the digitised signals to the calculating unit;
• cutting off the digitised signals into pulses, characterising each pulse to obtain primary characteristics and secondary characteristics;
• gathering the pulses into pulse blocks;
• for each pulse block:
• gathering the pulses as a function of their primary characteristics to produce primary groups;
• for each primary group:
• calculating primary characteristics of primary groups as a function of the primary characteristics of the pulses gathered in the primary group;
• gathering the primary groups as a function of the primary characteristics of primary groups to produce secondary groups;
• gathering the secondary groups as a function of secondary characteristics of the pulses gathered in each secondary group to produce tertiary groups;
• detecting at least one radar, each tertiary group being considered as a radar or a radar mode.
