摘要: A motion sensing method and apparatus includes a housing enclosing a microwave motion sensor including an antenna, and a security system. The antenna may be a patch antenna which includes microwave radiating elements for transmitting and receiving a microwave signal for sensing motion. A reflector is attached to the housing and positioned above the antenna for downward shaping of the microwave signal. The microwave radiating elements together with the reflector provide a radiation pattern where a main beam is transmitted in a direction orthogonal to a surface of the antenna and a sided lobe is transmitted downward in amplitude below the microwave motion sensor. An alarm circuit indicates when the microwave sensor detects motion in armed mode, and a masking circuit indicates when the microwave sensor detects motion in a mask zone when the security system is unarmed. A second sensor may be positioned beneath the microwave motion sensor.

摘要: A microwave direction of travel detector and method of detecting the direction of an intruder in a protected region. The microwave direction of travel detector transmits and receives, by a microwave transceiver a microwave signal directed toward a protected area. The microwave return signal is modulated by a moving target to produce a Doppler signal. The received Doppler signal is amplified by a chain of amplifiers having two or more amplifiers coupled to the microwave transceiver. A controller monitors the output of each chain of the amplifiers. The microwave sensor is configured for parallel sampling an amplified Doppler signal output from each amplifiers having a low signal output and each successive chain of the amplifiers a successively higher signal output. The controller determines if there is a direction of travel motion from the intruder and sends an alarm.

摘要: A dual mode motion sensor for detecting both motion of a moving target and a range of the moving target. The dual mode motion sensor normally operates in a pulse transmission mode. If motion is detected, the sensor automatically switches to a frequency modulated continuous wave transmission mode. This will allow the sensor to determine the range of the moving target. The sensor includes a microcontroller that compares the determined range of the moving target with a predetermined maximum detection range. If the determined range is outside or exceeds the predetermined maximum detection range the sensor will ignore the motion. If the determined range is within the predetermined maximum detection range, an alarm will be generated.

摘要: A microwave direction of travel detector and method of detecting the direction of an intruder in a protected region. The microwave direction of travel detector transmits and receives, by a microwave transceiver a microwave signal directed toward a protected area. The microwave return signal is modulated by a moving target to produce a Doppler signal. The microcontroller monitors the output of the amplifier chain and stores the signal and compares it with previously stored signals. If the amplitude is increasing or decreasing over a preset time period, this would indicate that the target it approaching or receding respectively and an alarm would be generated by the microcontroller.
