Fast response Retrodirective Radar

This paper shows the ability of an all analogue Retrodirective Radar, the first of its type, to provide continuous surveillance and near instantaneous target acquisition while automatically beam steering in real time onto a target which is presented to it. Assessment of the phase conjugation unit shows that the Radar is capable of operating either in CW or in pulsed mode. Test results are presented which show that Retrodirective tracking of targets travelling at speeds in excess of 780 m/s is possible. To confirm tracking ability bistatic results of a small near field target are presented, and the capability is also shown to extract the position of the near field target with only very simple calculations, with no DSP circuitry required.
