Barometric Pressure Sensors
-
Barometric pressure sensors measure fluctuations in the pressure exerted by the atmosphere. The sensors require protection from condensing humidity, precipitation, and water ingress. They are typically housed with the datalogger inside an environmental enclosure. If the enclosure is airtight, the sensor's pressure port must be vented to the atmosphere.

Shield Level / Pathloss Equipment
SG1000B/PR1000A
-
The SG1000 Signal Generator and PR1000A Preamplifier have been designed to simplify the measurement of shielding integrity in a shielded enclosure. When coupled with a high stability spectrum analyzer and an appropriate selection of test antennas, the SG1000/PR1000A combination can measure shielding effectiveness at all of the NSA 94-106 (supersedes NSA 65-6) defined test frequencies from 1 kHz to 10 GHz.The PR1000A amplifies the received signal from the test antenna and overcomes the high noise figure of the companion test receiver or spectrum analyzer. The PR1000A will ensure that the system noise figure will be less than 4.5 dB at all test frequencies from 1 kHz to 10 GHz. When used with a spectrum analyzer measurement bandwidth of 100 Hz, the system exhibits a sensitivity of -150 dBm at the test antenna output.To overcome high cable loss between the test antenna and the PR1000A assembly at 10 GHz, a remote low noise pre-amplifier (Praxsym PN 310-010091-001) is mounted directly onto the 10 GHz antenna.

Fluctuation Sound Analysis Function for O-Solution
OS-0526
-
Although the magnitude of the sound is not so large, there are many “unpleasant sound” in the world. For example, “rattling” and “humming“ sounds generated from interior items while driving a car, or abnormal sounds such as “buzzing“ sounds that can be heard in the rotation sound of a small motor, etc. Sounds with significant temporal fluctuation often feel unpleasant even the magnitude of sound (level) is not so large.

Mobile Sound Ranging Array
MSRA
-
In a peer to peer conflict, weapon location radars used for counter battery purposes will be extremely vulnerable.With aerial/satellite based surveillance available for the opponent, radars will be seen. With electronic warfare means being omnipresent, radars will be triangulated and jammed. There is an urgent need for 24/7 persistent surveillance with (preferably) passive sensors. With mobility being the key for survival on the battlefield, rapid re-deployable, or even truly mobile sensor capabilities are required. Therefore, the traditional sheer sound pressure based sound ranging capability becomes obsolete, as the triangular footprint of the sensor nodes is too large to be installed on a manned, or unmanned platform. With the trend towards longer ranges and “shoot and scoot” drills, the concept of capturing the muzzle blast noise becomes questionable, as the speed of sound is too slow to provide timely localizations.
