The anomaly causes a return wave pulse.

The second return signal is processed so as to isolate a second return pulse corresponding to the object.

The return signal includes a return pulse from an object within a detection area of the system.

One way of generating the compensating pulse is by delaying a horizontal retrace pulse (36).

The first return signal is processed so as to isolate a first return pulse corresponding to an object within a radar detection area of the positioning system.

Each return pulse is integrated sequentially by a single detector and processed by heterodyne reception and synchronous demodulation.

In some embodiments, the pulse can be transmitted with an antenna in a radar system, and a return pulse can be received and processed.
