1. General
Radar Beacon (Racon) is an X/S band frequency agile Racon. The dual band frequency agile
operation provides immediate response to radars in the service area. Automatic scaling of the
response code matches the range setting of the ship’s radar, signal processing logic is employed to
prevent Racon from responding to side lobes from nearby radars while only responding properly to
beam (main lobe).
The built-in computer calibrates the frequency precision regularly to ensure
transmission frequency is correct even if the Racon has worked continuously for a long time.
Racon is composed of a cylindrical cast and base made of FRB (Fiber-reinforced polymer is a
composite material made of a polymer matrix reinforced with fiberglass) that houses electrical
circuit boards. The combined X and S band slot antennas are mounted on the top of the base casting
and are protected by a high strength and corrosion resistance dome (see figure 1).
2. Composition of Racon
The Racon receives X & S band radar pulses from an approaching vessel and responds by
transmitting an identifying code sequence, usually in the form of a Morse code letter. The codes
received by the vessel’s radar will produce a trace on the radar display as a line of dashes and dots
(forming the Morse code letter) from the location point of the Racon.
The Racon is powered from an external nominal 12V D.C. source. It will operate with
input voltages that range between 9V and 24V. The system block diagram is shown in figure 2.
As indicated by figure 2, Racon is composed of six modules namely:
1. The Antenna module
2. Microwave receiving and transmitting module
3. Logarithmic amplifier and frequency discriminating module
4. Frequency correcting and code modulating module
5. Computer module
6. Power supply converter
PHALCON EXNCJMK2 Manual Page 2 of 8
The following is a briefing on their respective functions:
2.1 Antenna module
Antenna is used to receive a signal from radar and transmit its signal to the radar. The two
antennas for the two bands are omni-directional. The X-band works in the horizontal polarization
and the S-band in both the horizontal and vertical.
2.2 Microwave receiving and transmitting module
There are X and S band receiving and transmitting modules in Racon. It includes a receiver
front end consisting of the circulator, the balanced mixer, the local oscillator. It employs medium
frequency for stabilizing purposes, intermediate frequency preamplifier with low noise, a
transmitter consisting of voltage control oscillator and multi-lever power amplifier.
2.3 Logarithmic amplifier and frequency discriminating module
The logarithmic amplifier which is made up of high stable integrated circuits is designed to
have a wide dynamic range (near 60 dB) and satisfactory signal fidelity for the purpose of ensuring
precise data processing by the onboard computer. The frequency discriminator, which is made up of
wide-band phase detector and timing cable converts frequency into voltage
2.4 Frequency correcting and code modulating module
This part consists of circuits which track and hold signal in real-time. The circuit which
identifies the signal pulse-width, and the circuit which generates and modulates the code.
Information such as the signal frequency, pulse width and amplitude is delivered to the computer
module via the interface circuit within Racon.
2.5 Computer module
This module has the following functions:
Side lobe suppression
Frequency accuracy correction
Sending information to a computer or programmer that is linked through theconnection box on:
a. Power converter
b. Transmitter/Receiver
c. Frequency accuracy information
If any of the above information is faulty, this module will generate an audio alarm. End-users
can change Racon’s code, Service Time, Sleep Time and sensitivity through the same
connection.

EExe Junction Box
The Phalcon 2000EXNC may be wired into an EExe Junction Box.
The 6 way Power Cable and the 9 way Data Cable are connected within the EExe Junction Box via two EExe glands.
A third (blanked off) M20 tapped hole on the Junction Box is used to connect to the system via a customer-supplied cable and gland.
The cables from the Phalcon 2000EXNC can be cut to minimise excessive length.
As the cables are flexible it is important to ensure that they are tied to the structure to prevent the individual cores from fracturing due to continuous bending by wind or by vibration / movement
The EExe Junction Box may be fixed onto an optional stainless steel plate (PML Part Number W-74605) which is mounted using the existing threaded studs of the Mounting Kit. Extra M12 nuts, flat washers, and spring washers will be required to fit the plate onto the studs plus four M6 x 30mm cheese head screws will be required to mount the JB onto the plate.
