ABSTRACT:
There is disclosed herein a system for reflecting electromagnetic radiation emanating from a doppler-based radar source toward the source whereby at least a portion of the difference between the emanating and reflected signal is continuously varied between preselected limits by causing the reflector to oscillate along the beam axis. The reflector is moved between approximately 0.001 and 0.250 inches and at a frequency mix ranging between about 2,000 Hz and 15,000 Hz. The reflector is mounted to a reciprocating system which is provided to drive the reflector.
