The green indicator light at upper left is the power status indicator, and below that is the switch that turns the MADAR MCP on. Right below this (cannot be seen) is the SPI (sensor pulse input)  jack. To its right is the "Arm" switch or pulse bridge that keeps the system from being activated during maintenance, etc., and allows data tapes and recorders to be left in standby record mode. When the arm switch is turned on, the system is ready for the detection pulses from the Sensor Cell Module, which you'll see later. On the right side of the panel is the blue indicator light which comes on with the alarm signal when the system is triggered. The switch to the bottom left is the relay switch, which allows the MCP to lock the DPDT relay in the "on" position when the system is activated. The alarm side of the MCP is now running and the green LED, the alert signal, 110 VAC circuits for the data recorders are all "on". The switch below the blue LED  turns off the alarm signal only.

On the main floor and office north wall are the Quad Monitor, SCQ-041 Quad Processor, Panasonic VCR, TLC2100 Time-Lapse Surveillance VCR, and the RWWV Receiver which is connected to a 150' horizontal antenna outside.

The North Wall


(Left) The Quad Display, (Right) Cam 3 view is selected

The image at upper left is the Quad Display Monitor. In the Camera 1 position is from the live images from the security camera showing the room below where the sensor and MCP are located. Camera 2 position is from downstairs also and is the live feed from the MADAR computer with the TES 1392 E-M device measuring the electromagnetic field in milligaus or microtesla. The bottom left is the miniature camera view of the primary sensor displayed on Camera 3 position. (see enlarged photo at right). Finally, the bottom right on Camera 4 is the fluxgate magnetometer readout.

There are two VCRs running.  The SVAT Quad Processor displays four images on the monitor that has a video time dub onscreen and an audio WWV signal from Fort Collins, Colorado. The main VCR is a surveillance type, a GYYR TLC2100, that records the Quad presentation for 7 days. The tapes are replaced every week and cataloged and stored for 12 weeks, then re-used.  During an event, the other video recorder which is manually activated, automatically shuts off after two hours.  This unit also records the WWV time code on the audio, but it has an extra channel that records transmissions from aircraft flying over the region.

One floor below the North wall rack  is a "cubby hole" 4' by 11' that houses stored data tapes and other materials and also houses the heart of the MADAR system. Isolated by distance, from accidental triggering, is the main sensor, the Sensor Cell Module. Also located here are the Switch Sensor Relay Module, Proximity Alarm Module, the MADAR Mode Control Panel, audio data recorders, TES-1392 E-M meter and data logger, computer, digital to analog converter, and feed lines to the upstairs equipment.

The "Cubby Hole"

The Sensor Cell Module houses a very sensitive 254 mm magnet variometer, monitored around the clock by a verticle light beam from an LED on the bottom and the photoelectric cell on the end of a small cable at the top.  The Switch Sensor Relay Module is isolated from the detector unit and the PE cell on the small line is situated in "light tube" which isolates the chamber so that the CM208C minicam can observe and  record the actual sensor movement.

The Proximity Alarm Panel Module

When the MADAR system is triggered, the sensor movement that caused this produces 12 VDC pulses that are sent to this module which displays red flashes on the LED indicator. When this is occurring there are also corresponding clicks or pulses in the audio range that are recorded. All this indicates that the source of the E-M disturbance is "live" and the proximity is close enough to trigger the system. The sensor line plugs in the input jack on the bottom left of the MCP and the outgoing pulse that triggers the whole system on the Mode Control Panel exits the output jack on the right. Since the system doesn't record the first pulse, the one that triggered it, this is referred  to as "the phantom pulse". The data can be graphically displayed and studied using Audacity software.

TES T-1392 Data logger

This device has two applications for the MADAR Project.  One, it gives E-M readings during the event which are graphically presented by computer, then fed to a digital to analog converter, which feeds the video to the Quad Processor and both VHS recorders. When the MADAR alarm is activated, one of the chores of the operator is to hit the RECORD button on the T-1392 which starts the data logging process. After the event one can see the actual readings for the entire period. Prior to an event the data logger is programmed and the scan rate is set. All the operator has to do is turn it off at some point after the alert is terminated.  The specifications for this device are presented below.

Model 4 Geiger Counter

The Mineral Labs Model 4 geiger counter has a harness line to a dedicated computer which is online 24/7 to the Radiation Network.  The readings are displayed on the map (see below) which is refreshed every 60 seconds. Since the geiger counter is also running 24/7, when the MADAR-II goes into alert status the data recorder starts to record the counts per minute and up until the cassette tape runs out at 45 minutes.

In the region, law enforcement (police, sheriff, state police) and Air Route Traffic Controllers at the local airport have been advised in advance to forward calls received regarding unidentified aerial phenomena. When an event takes place it will be up to the operator to contact the airport ARTC's to check for radar anomalies. If anything is discovered, FOIA action can provide recordings of the radar display which our experts can view and analyze.
