into the DSP memory using the host computer that runs
the LVRTS software. Electrical power is supplied to the
RTM by the Power Supply, Model 9408, through a multi-
pin cable that connects to the back panel.
Model 9630 – Analog/Digital Signal Combiner
The Analog/Digital Signal Combiner is a compact
module designed to be installed into one of the slots on
the RTM of the Radar Processor/Display. This module
converts the clutter and interference generated by the
DSP of the RTM to analog format, and adds it to the
I- and Q-channel echo signals coming from the Radar
Receiver.
The Analog/Digital Signal Combiner has two
BNC-connector inputs to receive the I- and Q-channel
echo signals. It also has four BNC-connector outputs.
Two outputs provide the clutter and interference signals
added to the I- and Q-channel echo signals. The other
two outputs provide the I- and Q-channel, perturbed
echo signals. All these inputs and outputs are protected
from misconnections within the system. Test points are
available on the module's front panel to observe all these
signals using a conventional oscilloscope.
DC power is automatically supplied to the
Analog/Digital Signal Combiner when it is installed into
the RTM.
Model 9631 – Data Acquisition Interface
The Data Acquisition Interface is a compact module
designed to be installed into one of the slots on the RTM
of the Radar Processor/Display. This module receives
the I- and Q-channel echo signals of the radar, perturbed
or not, and converts them to digital format. It also
receives the PRF and synchronization signals as well as
azimuth information from the Radar Synchronizer /
Antenna Controller. All these signals are then routed to
the RTM for digital signal processing.
The Data Acquisition
BNC-connector analog inputs to receive the I- and
Q-channel echo signals. It also has two BNC-connector
digital inputs where the PRF and synchronization signals
are injected. A DB15 connector is provided as a digital
input for the azimuth information. All these inputs are
protected from misconnections within the system. Test
points are available on the module's front panel to
observe the input signals using a conventional
oscilloscope.
DC power is automatically supplied to the Data
Acquisition Interface when it is installed into the RTM.
Interface has two
