MADAR-II Sensor Module                                                  MADAR-III DataProbe


MADAR originally used vertical light beams and photoelectric cells for compass deviation monitoring to set off an alert and gather data. All of this work was based on 150 compass deviation cases involving UAP. MADAR-II operated the same way but brought in more advanced technology. But there was always only one MADAR. What we needed were many, affordable devices, at places all over the country or world, all tied into one network. And it was time to try some new methods.

It must be made clear that once the "sensor" is isolated from all other natural or man-made E-M sources, the very small reading one is left with is simply the Earth's own magnetic field. What we are then looking for is something distorting that field. Since the Earth's magnetic field doesn't vary more than 5 per cent from its static average, the "background" is perfect." The classic magnet variometer is a mechanical sensor...besides tending to be simple in construction and operation, mechanical sensors offer a bonus that helps improve the signal-to-noise ratio. They tend to be unresponsive to high frequency fields, which is good; we are only interested in slow changes in the steady field." The resolution is typically 0.1 gamma.

To put it another way, you don't want anything in your room, local environment, that has a E-M that is higher than whatever it is that UAOs produce at times. You want your "Field" number to be as low as possible. A higher field number will mask the natural field and make it very difficult, if not impossible to detect UAP.

In April of 2016  I conceived of MADAR-III, an affordable way to get many devices into the field, and we soon took a different course. So, by April of 2018, two years later, we were operational and had a device that used a triple-axis magnetometer to detect the UAP and also be able to monitor compass heading changes. Both columns are assumed to change in direct proportion. It works. But we may switch the roles periodically to see if it makes any difference. All of this can be done without returning a device for new programming. All this can be done by rebooting new software.

But right now we have learned not to send devices out with low limits settings because many go into alert status right away. And presently we cannot do remote reboots when the MADAR-III is locked into Alert mode. The operator has to unplug, wait 10-15 secs, then replug. But the device usually goes right back into alert because the limits are too low. So we then used 30 as the default setting, or rather the initial setting. Then if the device remains stabil we leave it alone for a while. We watch these devices very closely and every Monday I do the Node Inventory. If I see no alerts in 60 days I make a note to lower the limits in another 30 days.

I would rather see false alerts than no alerts. The former tells us the device is working, whether picking up local EM fields or UAP. The latter could indicate a bad Chinese sensor, a bad computer, a wiring problem, etc. When we drop the limits (now called trigger) settings, we usually go in 10 units increments. Within 24 hours if there are no Alertstarts, we can drop the settings even more. But once we are in the 10-20 range we are more comfortable. Just the opposite occurs when we raise the limits to the 50 to 60 range. I truly believe if the operatot uses an AM radio tuned to the left side of the dial, he will be able to find a more radio quiet place to put the device. An E-M meter should show a field of under 0.5 mGa, but a little higher is not that threatening.

In the original device the sensor had to be carefully placed in the same orientation in its case and be connected with a ribbon-type computer wire to the computer pins. Lots of possibilities for error and bad connections. It also required the use of the Chinese sensors which varied in price but not in direct proportion to quality. Our new sensor board is our board and uses the best available parts. It also insures the sensors are aligned the same way on all devices. So in the case of most applications the operator will place the device squarely on a shelf, and in my case along the south wall. But if the limits settings become a problem, the device may need to be reoriented a quarter turn (either direction).

So, with plug and play, alignment shouldn't be an issue, but sometimes it is. All due to way the systems looks at the local geomagnetic and electromagnetic field. So find your niche. Set your "mousetrap" to trigger very easily and raise the limits 5 points, then just wait. We have a lot to learn.  UAP produce EME. We have known it for about a century.
