... design. It is a way of representing the radar parameters and relevant quantities
in terms of logarithms. The unit dB is named after Alexander Graham Bell,
who originated the unit as a measure of power attenuation in telephone lines.
By Bell’s definition, a unit of Bell gain is
... of amplitude modulation which, for an ideal
beam shape, is directly proportional to the offaxis angle En. The sense of the error angle is
established by comparing the phase of the detected modulation with a synchronized reference
scan signal transmitted from the radar to the
missile by ineans of a f ...
... The R60D RVIT (Rotary Variable Inductance Transducer) is a
DC operated non-contact angular position sensor. Operating on
a ±15VDC supply, the R60D provides a smooth ±7.5VDC
output proportional to angular position over a ±60 degree
The RVIT proprietary design utilizes a set of four pri ...
... SECULIFE DFBASE used for functional testing of external
defibrillators. The delivered energy is measured by a builtin simulated load similar to the human body (50 ohms).
Furthermore, rapid and immediate viewing and selecting of
the desired ECG signal types and test data is possible.
To determine the ...

1． If LCD displays “OL” when
you use manual range, it
means over range, should set
the knob to a higher range.

... within the gate. Because the detector takes ten nanoseconds or more to reset after firing, we have made no
attempt in our ladars to date to enable the detector to
fire more than once per laser pulse. The detector either
fires once or not at all. Thus, if the detector fires from
a noise source before ...
... Figure 3 shows a system used in this study that basically consists of two antennas, one
transmitter and one receiver mounted on a tower keeping a certain distance from each other.
The target is mounted on a dielectric support and this one is mounted on a positioner which
will allow recording the RCS ...
The AN/FPS-16 is a highly accurate ground-based monopulse single object tracking radar (SOTR), used extensively by the NASA manned space program, the U.S. Air Force and the U.S. Army. The accuracy of Radar Set AN/FPS-16 is such that the position data obtained from point-source targets has azimuth and elevation angular errors of less than 0.1 milliradian (approximately 0.006 degree) and range errors of less than 5 yards (5 m) with a signal-to-noise ratio of 20 decibels or greater.
