Real Time Signal Sampling and Recovery Using Engineered Electromagnetic Interference

The invention is a probing instrument that can recover a signal (normally a signal would be a 3D environment such as a room, a building, a city, etc.) by illuminating the signal with electromagnetic radiation structured in space and time according to the excitation signals applied to the corresponding antennas of the transmitters and detecting reflections with a set of receivers. The interference of propagating electromagnetic waves generated by a set of transmitters is used to sample signals in real time. A signal here is anything in the propagation medium that causes the electromagnetic waves to reflect. The data y, measured by a set of detectors, corresponds to the inner product of engineered wave interference sampling matrix A and the signal x described in short form by the equation y=A·x. Sampling happens at the speed of the propagating waves in real time and signal recovery is attained by simple aggregation of the matrix A and the measured vector y with the option for computational optimization.
