Latest Patents

Steven J McCoy holds a patent for a range-gated radar motion detector. This device combines an FCC approved homodyne pulsed range-gated radar (RGR) detector with a passive infrared (PIR) detector. The RGR detector transmits narrow microwave pulses at a predetermined pulse repetition frequency (PRF). These pulses are reflected by targets, allowing the RGR detector to sense moving human-sized objects within specific ranges. Objects beyond these ranges are not detected. The system employs a pulsed microwave oscillator triggered by a system clock, with a delay of 3 to 100 nanoseconds. Each pulse lasts between 3 to 20 nanoseconds and has a half-sine envelope shape. The RGR detector uses a homodyne detector and shares an antenna with the transmitter. The receiver range is determined by the delay between transmitted pulses. The detected baseband signal is amplified, processed, and filtered to frequencies below 100 Hz. An alarm condition is indicated if the output exceeds a predetermined threshold, which can be adjusted based on range and object size. The PIR detector operates conventionally, and its output is logically combined with the RGR detector output to minimize false alarms.
