  • Publication number: 20080111729
    Abstract: A plurality of multi-tone CW radars are used to generate a swath of ranges to a moving object or individual behind a wall or building structure in which the overlap of the range swaths from spaced-apart radars determines the location of the moving object or individual. A histogram of the swath overlaps is used to generate a display of the path of the moving object or individual.

  • Publication number: 20070024487
    Abstract: A multi-tone CW radar (14) is used to project signals from an antenna (22) and to receive returns with the same antenna. The phase differences between the outgoing signals and the returns are analyzed to determine the existence of motion and the range to a moving object (10). A model is made which has range as its major parameter. A waveform associated with the phase difference between outgoing signals and returns for one of the tones is compared to templates produced by the model to determine which has a range that most closely matches. By varying the range parameters, when a match is detected the range to the object can be obtained even if its motion is pseudorandom. If the range is measured with multiple units it is possible to measure the location of the object. This can be done assuming a grid and algorithmically combining the ranges from the units.

  • Publication number: 20060261818
    Abstract: A robust, easily deployable, covert, passive intrusion detection system uses one or more E-field sensors to detect the presence of a moving individual and to provide an indication of the presence of the individual adjacent the sensor based on E-field distortion produced by the individual. Single-ended and differential E-field sensors with noise canceling and a guarding circuit provide sufficient sensitivity, with filtering from 0.5 Hz to 8.0 Hz selecting only human intruders. Either visible or invisible flashing light sources at the sensor indicate the presence of a moving individual at the sensor, thus to provide intruder location without the necessity of providing a geolocation system.

  • Publication number: 20050122118
    Abstract: The invention is a detection system comprising inexpensive, miniaturized sensors for detecting electric field (E-field) disturbances. Such sensors are easily and covertly deployable and have low power consumption. The devices may incorporate visual or audio alerts and can include communications hardware for transmitting data for further processing of the electrostatic events.

  • Publication number: 20050062605
    Abstract: Techniques that provide relatively low cost and complexity remote sensing capability are disclosed. The sensors can be easily deployed and monitored by a single operator, with minimal opportunity for human error, and without the need for a visual display. During deployment, the sensor is adapted to record a message including a verbal description of the location. Other useful information, such as the operator's name and sensor type may also be included. The voice locator message is transmitted in response to the sensor triggering, thereby allowing the operator to hear the location of the triggered sensor. Additional device functionality may include sensor signal analysis (e.g., confidence testing) and a power conservation. The devices have numerous applications (e.g., military and SWAT operations), and can be adapted to detect intrusion, perimeter breach, movement, vehicles, and other detectable events.

  • Patent number: 6633254
    Abstract: A self-modulating, remote, moving target detector for intrusion alarms, vehicle detection, and remote speed and distance measurement that includes a remote continuous wave radar transceiver that is used to detect moving targets. The same frequency used for the radar transmission is modulated in a continuous manner in order to transmit radar data concerning a moving target to a remote location away from the radar transceiver. The transceiver oscillator is self-modulated by the reflected signal received from a moving target in the transceiver and retransmitted such that the primary radar signal becomes the information carrier concerning the moving target, which is received remotely, in order to activate an alarm or a display system showing the moving target. The system could be utilized with any frequency from audio to light, with RF and microwave of primary interest.

  • Patent number: 4386275
    Abstract: An apparatus and method for detecting the presence of a heat emitting body within a region provides for the mounting of a cylindrical shroud having an apertured circumference within the fields of view of an infrared sensor responsive to changes in thermal energy received as a heat emitting body enters the fields of view. The motion of the heat emitting body through the fields of view provides different levels of radiation received at the sensor thereby developing a current imbalance at the output of the sensor which is used to actuate switching circuitry for controlling an appliance which is to be actuated upon entry of a heat emitting body into the field of view of the sensor.
