Overview
Introduction
The MPS-4100 Microwave Protection System provides exterior perimeter
intrusion detection coverage. The MPS-4100 detects movement within a
microwave field between the Transmitter and Receiver and initiates an alarm to
alert responding personnel.
General description
The MPS-4100 bistatic microwave system consists of one Transmitter (Tx) unit
and one Receiver (Rx) unit. The Transmitter is a Dielectric Resonant Oscillator
(DRO) designed to radiate microwave power at 10.525 GHz. This oscillator is
pulse modulated (on-off switched at a 50% duty cycle) with a selectable frequency
of 3, 4.5, 7.5, 10.5, 18 or 27 kHz. The transmitted energy is received and
processed by the Receiver using Phase Locked Loop (PLL) technology. An intruder
moving in the pattern causes variations in the signal and is detected. This is
referred to as multi-path detection.
