Abstract: A monitoring system of the integrity of a pressurised pipe by at least one pressure pulses generator that is hydraulically connected to the fluid in the pipe. Each generator comprises: one first tank and a second tank that maintain the fluid respectively at a first and a second pressure values. The first value is smaller, and the second value is greater than the predefined pressure value of the fluid in the pipe. The first and second tanks generate respectively a negative pressure pulse, caused by the passage of the fluid from the pipe to the first tank, and a positive pressure pulse, caused by the passage of the fluid from the second tank to the pipe. A pressure transducer is designed to measure the pressure values of the fluid in the pipe and to convert the negative or positive pressure pulses generate by the generator into respective recorded acoustic signals. A measurement station is placed along the pipe to detect the acoustic signals.

The method includes transmission of at least one radar wave by a single radar device positioned at a predefined distance from a receiver device applied on the object/structure, reception, by the radar device, of a complex signal consisting of the sum of the signal reflected from said receiver device and of one or more interfering signals generated by one or more corresponding targets substantially stationary and substantially positioned at the same distance from the radar device, separation of the interfering signals from the reflected signal.
