RACOR TARGET DESCRIPTION
 

RACOR TARGET DESCRIPTION

    The RACOR target is a reliable solid state self contained assembly that has been successfully functioning with many instrumentation radars.  The RACOR electronics mixes the transmitted radar signal with a stabilized crystal oscillator and generates two side bands that are re-radiated from the antenna toward the host radar.  The reply will be transmitted at a frequency of Ft +/- Fo (Ft=radar transmitter frequency, Fo=oscillator offset frequency).  The oscillator frequency can be selected from about 30 MHz to several hundred MHz.  It should be far enough from (Ft) so that the skirts of the radar receiver passband will reject the clutter return (backscatter at the transmitted frequency).  This eliminates all clutter when the receiver has been tuned to accept the RACOR return.

    The receiver may be retuned to the RACOR frequency (Ft +/- Fo) either by manually setting the skin local oscillator or with the beacon local oscillator.  A Fredwal RACOR radar beacon modification kit is also available for radars that do not have a beacon mode capability.
