ABSTRACT:
A radar system comprising an RF transmitter and receiver means for mounting in a moving carrier for transmitting RF energy and receiving RF energy returns and a non-rotating modulating radar reflector which has a lens means for focusing incident impinging RF energy onto a spot opposite the incident side and a plurality of solid state modulating radar reflectors positioned at the spot locations for selectively reflecting the RF energy and dissipating the RF energy for providing RF energy returns modulated with a lens identification code and frequencies for determining true ground speed, range, glide slope, and azimuth position. The solid state modulating radar reflector including a microwave section having open back and front ends, a load resistive means at the back end, a PIN diode adjacent to the load resistive means and a modulating power source for modulating the PIN diode to provide at preselected intervals virtual shorts at the open end of the wave guide for reflecting modulated RF energy returns directly to the source of RF energy.
