Abstract : The patent describes a radar reflecting and modulating system using unbalanced spiral conductors. A pair of conductors are wound and interleaved on a conical surface with one spiral terminating in a zigzag configuration at the base of the conical surface. The conductors are connected to a variable impedance load which is controlled by a pair of voltage sources whose outputs have different time dependence. The control voltages provide bias to interconnected varactors which are connected to the spiral conductors.
