Title: The Innovations of John F Chaney
Introduction
John F Chaney is a notable inventor based in West Covina, California. He has made significant contributions to the field of video processing technology. His work primarily focuses on enhancing the performance of constant false alarm rate (CFAR) processors.
Latest Patents
John F Chaney holds a patent for an "Extended target-log CFAR processor." This innovative device utilizes a tapped delay line that operates as a 'sliding range window.' It provides tap outputs corresponding to the center of the delay line and a predetermined number of discrete range cells on either side. A 'least of' circuit responds to all taps except the center tap of the delay line. The minimum signal present on these taps is outputted and subtracted from the signal of the delay line. This circuit adaptively excludes target and ground clutter bias, providing a normalized CFAR signal output. Additionally, a circuit arrangement is included for digitally mapping the 'least of' signal values over a predetermined threshold. The digital map output is converted to analog, providing the scaled 'least of' signal to be subtracted from the central range cell and controlling the threshold of response of the mapper.
