Hardware Interface to Connect an AN/SPS-65 Radar to an SRC-6E Reconfigurable Computer

A hardware interface is designed, developed, constructed, and tested to interface a naval radar to the SRC–6E reconfigurable computer. The U.S. Navy AN/SPS–65 radar provides in-phase (I) and quadrature (Q) channels along with the AGC voltage to the hardware interface in analog form. The hardware interface receives a sampling clock from the SRC–6E and in turn performs the requisite attenuation and digital conversion before presenting the signals to the SRC–6E through its CHAIN port. The results show that the SRC–6E can effectively generate a sampling clock to drive the analog-to-digital converters and that real-time radar data can be brought into the SRC–6E via its high speed CHAIN port for performing high speed digital signal processing
