4. System Theory of Operations
The following sections describe the system theory of operations. System theory is used to
describe software controls, signal flow and the relationships of sub-assemblies. System theory is
divided into the following categories:
1. COBRA Software
2. Primary Power Supply and Distribution
3. Interlock Circuitry
4. Transmitter Control and Transmit
5. Transmit Waveguide and Star Waveguide Assembly
6. Receiver Signal Flow
7. Antenna Control and Angle Acquisition
8. Communication Interface
4.1. COBRA Software
The Ranger-X5 local user station operates through the EDGE Software through an interface to
the COBRA application software and the Local Control Interface (LCI). COBRA processes all
operator commands from either the local or remote operator EDGE workstations and routes them
to the appropriate radar control circuits. The I/O modules collect information on radar
performance and status, and provide basic, bit level control to specific subsystems. The COBRA
program also correlates and processes information and procedures from the BITE sub-system,
controls the Antenna/Pedestal operational parameters, and performs basic radar control
functions. The Aquarian Servo Controller, the UDC / Transmit Control Unit, and the COBRA
software seamlessly integrate with the IQ2-IFD and IQ2-DSP, communicating by standard
Ethernet protocol.
The EDGE workstation(s) input the commands and pass system status signals to and from the
system units such as the transmitter/receiver system and the Antenna system. In LOCAL mode,
manual inputs for Antenna drive commands come from the EDGE operator control. The EDGE
Software and the COBRA software can display all radar BITE data on the KVM screen. The
COBRA software also sends the BITE data to the EDGE remote host processor.
The interface, internally and to external workstations and processors, is a 10/100/1000 Ethernet
data communications circuit. See Figure 62 for a graphical depiction of the COBRA software
Architecture and communications protocols with other radar units.
