1.0 Introduction

The MicroWave 330 is part of the INTREPID™ Series II family of products. It is digital microwave field
disturbance sensor providing perimeter protection for open areas, gates, entryway, walls and rooftop
applications. It provides volumetric detection of human intruders with minimal environmental nuisance alarms.
Advanced digital signal processing (DSP) allows continuous monitoring of intrusion alarm and tamper switch
status, received signal strength for path fault and detection parameters. A system controller such as the Relay
Control Module II (RCM II), Control Module II (CM II), Graphic Control Module II (GCM II), Perimeter
Security Manager (PSM) or SDK (Software Development Kit) is required to poll and configure alarm sources
from MicroWave 330 for annunciation.

MicroWave 330 operates at K-band (24.125 GHz) frequency, achieving superior performance to X-band
sensors. Because K-band is 2.5 times higher the X-band, the multipath signal generated by an intruder is more
focused, and detection of slow-moving intruders is correspondingly better. At K-band frequency, the unit also
has low susceptibility to outside interference from air/seaport radar or other microwave systems.

MicroWave 330 communicates with other INTREPID Series II devices using RS422 communications. This
communication can be done over 22 or 24 gauge stranded shielded twisted pair wire (max 5,000 feet [1,500m]
between devices) or with fiber optic devices. The address of each MicroWave 330 is set by a dip switch on the
receiver circuit board.

MicroWave 330 operates from 10.5 to 60 VDC @ 2.5 Watts with a minimum startup current of 250mA. The
operating currents with standard power supplies are: 12 VDC @ 125mA (Tx) / 208mA (Rx), 24 VDC @ 63mA
(Tx) / 104mA (Rx) and 48 VDC @ 32mA (Tx) / 52mA (Rx).

3.0 Principles of Operation and Detection

3.1 Description

The MicroWave 330 Transmitter radiates amplitude modulated K-band energy that travels to the MicroWave
330 Receiver where it is detected. A microprocessor and proprietary algorithms provide powerful Digital Signal
Processing to recognize the unique bi-static digital signatures of intruders walking, jumping, running or crawling
through the detection field. Targets are classified and scored in real time at each sensor and stored in the
receiver’s flash memory. When an intruder approaches the beam the energy at the receiver changes in signal
amplitude directly related to the targets size and density allowing the sensor to discriminate between targets.
MicroWave 330 will alarm on average sized humans walking, running or crawling on hands and knees through
the detection pattern. Field adjustments can provide alarm on larger or smaller targets, depending on the specific
site requirements. Operation of MicroWave 330 is illustrated in Figure 2.

3.2 Range of Operation

A single MicroWave 330 may cover a distance of 800 feet (244m). The receiver is equipped with automatic gain
control (AGC), which automatically adjusts receiver for the distance to be covered and sets the Path Fault
parameter.

Typical maximum width protection pattern of MicroWave 330 is shown in Figure 3 for mounting height of 2.5
feet (.76m) above smooth earth.

maximum and Receiver “Sensitivity” control is set to maximum

Figure 4 illustrates how pattern width varies with Transmitter-Receiver distance and sensitivity setting. Actual
patterns will vary somewhat with site topography and surface condition. Generally, lower mounting height or
rougher surface will increase pattern width. For example, if the total link distance is 500 feet (152.4m) and the
sensitivity adjustment set to mid-point, Figure 4 indicates the detection pattern width to be 7.5 feet (2.3m).

Maximum width will be when Transmitter-Receiver distance is at

Figure 3 – Typical Maximum Horizontal Pattern

Vertical protection pattern will also depend upon Transmitter-Receiver distance, mounting height and
“Sensitivity” setting. Actual patterns will vary somewhat with site topography and surface condition. Typical
pattern height is 50 to 75% of pattern width. Approximate vertical protection pattern is shown in Figure 5. For
example, at 50 feet (15m) with minimum sensitivity the pattern height is 5 feet (1.5m).

3.3 Overlaps

Protection pattern below centerline will tend to fill area between beam centerline and ground except for a “dead
zone” immediately in front of and below Transmitter and Receiver. This zone is best protected by overlapping
links at ends and corners as shown in Figures 6.

Figure 6 – Overlaps and Dead Zone

Corner overlaps should be 30 feet (9.2m) minimum. Intermediate or in line overlaps should be 60 feet (18.3m)
minimum with a beam centerline offset of 18 to 20 inches (46-51cm). Basket weave overlaps should be 60 feet
(18.3m) minimum and a minimum of 5 feet (1.5m) off the fence (except for corners).

8 Version 0

Figure 7 shows amount of overlap required to detect against hands and knees crawling intruders, as a function of
“Sensitivity” setting. It is always recommended to keep the sensitivity setting at the lowest possible value to
minimize nuisance alarms but maintaining a high probability of detection.

DEAD ZONE - FEET

Figure 7 – Sensitivity vs Dead Zone

3.3.1 High Security Overlaps

For maximum-security applications where detection of prone “commando style” crawl is required, the
intermediate over-lap should be 60 feet (18.3m) minimum with parallel beam centerline offset of 18 inches
(46cm) maximum. The corner overlaps should be 30 feet (9.2m) minimum. Terrain flatness should be no more
than plus three inches or minus three inches deviation from a plane drawn between the transmitter and receiver.
The zone length (Transmitter to Receiver) should not exceed 400 feet (122m).

High security applications also use stacked link configurations to meet site requirements. A stacked link may
consist of two or more MicroWave 330 links or used in combination with the Model 300B link which operates
at X-band frequency of 10.525 GHz. A stacked link greatly reduces the dead zone and increases PD.

3.4 Transmitter Block Diagram

MicroWave 330T Transmitter consists of two major subassemblies – RF Assembly and Transmitter Circuit
Board. A block diagram is shown in Figure 8.

9 Version 0

The RF assembly consists of a Gunn oscillator, which generates K-band microwave energy and the parabolic
antenna system. The Transmitter circuit board contains voltage regulator and modulation circuit to drive the
microwave oscillator and a secure CPLD. Modulation frequency in Free Run Mode is selected from one of six
channels (A, B, C, D, E, and F) by a dip switch on the Transmitter Circuit Board.

The CPLD is responsible for the generation of the asynchronous modulation frequencies when the “Mode”
switch is set to “Internal” position and also for determining the quality of the signal provided on the tether when
the “Mode” switch is set to “External” position.

A “Test” terminal is provided on the Transmitter Circuit Board. Application of 5.0 to 14.0 VDC will cause
Transmitter to turn off and illuminate the red “Channel Error” LED, generating a test alarm at receiver. A green
LED on Transmitter Circuit Board indicates that power is on.
