Abstract
The invention refers to the analysis of a very high frequency radiation beam of electromagnetic waves. According to the invention, a network of conductor wires is placed in the path of a beam to be analyzed, the wires being interrupted at intervals by switches. One controls the conducting state of a diode and one blocks the others and one makes the position of the diode vary electronically and sequentially in the conducting state. The return signal received on a sensor R is used by detecting the significant characteristics of that return according to the position of the diodes in the conducting state.
Claims7
In an antenna beam analyzing system, a selectively reflective structure positioned in confronting relation to an antenna and comprising:
- a first plurality of coplanar conductors disposed in parallel spaced relation;
- a second plurality of coplanar conductors disposed in parallel spaced relation to each other and respectively orthogonal to the first conductor plurality so that the conductors form a matrix configuration having individual contiguous mesh-like units;
- means mounting the planes of the first and second conductor pluralities in spaced non-contacting relation;
- a diode array including individual diodes uniquely connected between a conductor of the first plurality and a conductor of the second plurality, each diode oriented parallel to the electric field of the antenna beam;
- and
- means for individually switching a small number of adjacent diodes to a first state while switching the remaining diodes to a second state, the switching means further addressing a different small number of diodes during sequential intervals in a predetermined pattern causing changing corresponding return signals to the antenna.
