Radar Target Tracking Interface
8112778 (9633-10)
The Radar Target Tracking Interface is a compact module
designed to be installed into one of the slots on the RTM of the
Radar Processor/Display. The module provides the lobe
switching control signal and the RF circuitry (bias tee and DC
blocking capacitor) required to perform lobe switching with the
Dual Feed Parabolic Antenna. To allow manual or automatic
control of the radar antenna rotation, the Radar Target Tracking
Interface is also used to intercept the rotation command signal
produced by the antenna controller before it reaches the
antenna motor driver.
The Radar Target Tracking Interface is provided with four SMA
connectors that provide access to the lobe switching RF circuitry. It also has two BNC-connector inputs (lobe
switch control input and antenna rotation command input) and two BNC-connector outputs (lobe switch control
output and antenna rotation command output). All these inputs and outputs are protected from misconnections
within the system. Test points are available on the module's front panel to observe the signals on the BNC-
connector inputs and outputs using a conventional oscilloscope.
DC power is automatically supplied to the Radar Target Tracking Interface when it is installed into the RTM.
