Fast time constant radar
WebConventional radar detection and tracking are fast-target automatic detector (FTAD), includes a first- used along with special automatic discrimination meth- threshold logarithmic detector incorporating a fast time ods. Webfast time constant. An electric circuit which combines resistance and capacitance to give a short time constant for capacitor discharge through the resistor. Circuit with short time constant used to emphasize signals of short duration to produce discrimination against low-frequency components of clutter in radar.

The FTC circuit is a signal differential processing module, which can automatically detect and retain the front edge of echo signal. After the processing of the FTC, only the leading ...
WebMay 14, 2024 · Fast Time Constant (FTC) is a processing operation that can be applied to a radar video signal to remove low frequency components, for example due to weather effects. The FTC processing will filter these low frequency components, so that only pulses that rise and fall quickly will be displayed. Radar TX time and On Time Reset Furuno … WebA fast-time-constant (ftc) circuit is a differentiator circuit located at the input of the first video amplifier. When a large block of video is applied to the ftc circuit, only the leading edge will pass. This is because of the short time constant of the differentiator.
