Abstract
A device for detecting frequency modulated continuous wave radar includes an antenna connected to a bandpass filter. The antenna is configured to receive frequency modulated continuous wave (FMCW) pulses within a predetermined frequency range. A frequency mixer is connected to the bandpass filter and a synthesizer and is configured to mix a signal from the synthesizer with an output of the bandpass filter to produce basebanded data. A high-pass filter is configured to isolate short pulses pertaining to the basebanded data, and a low-pass filter is configured to isolate long pulses pertaining to the basebanded data. A microprocessor is configured to set thresholds for comparison with the outputs of the high-pass filter and the low-pass filter.
