The detection coverage is largest midway between the transmitter and receiver.
The size of the detection coverage increases as unit separation increases (see
Figure a-5).
The coverage patterns in Figure a-5 are for human-size objects. Large metallic
objects, like vehicles or moving fence panels, can be detected beyond the
indicated envelopes. The pattern is approximately the same horizontally and
vertically, creating an elongated cylindrical detection field that is tapered at both
ends. However, the pattern does not extend below the surface of the ground.
Detection capability depends on the sensitivity setting, the transmitter/receiver
separation and mounting height, and the intruder profile (walking, creeping,
crawling, or rolling). For reliable detection of all intrusion profiles, the separation
between the transmitter and receiver must not exceed 100 m (328 ft.). This is
referred to as a high-security microwave detection zone.
At the maximum separation distance for bistatic microwave units, only upright
walking intruders are reliably detected. Microwave detection is NOT terrain-
following. Only line-of-sight detection is provided by bistatic microwaves.
Unit separation and the mid-point zone width
There is direct relationship between the separation distance of the transmitter
and receiver (zone length), and the diameter of the detection envelope at the
mid-point of the zone. The approximate beam width relationship for various
products is indicated in the following table.

Product Beam width relationship
MPS-4100 BW = ZL x 0.066
Microwave Series 14000 BW = ZL x 0.018
Microwave Series 16000 BW = ZL x 0.055
Microwave Series 24000 BW = ZL x 0.035
BW = beam width
ZL = zone length (i.e., unit separation)
