1.1.1.1. COBRA RCP Module
The COBRA Radar Control Processor (RCP) module controls the radar hardware through a
series of coordinated and supervised hardware Analog and Digital control modules. These I/O
modules connect to the RCU by Ethernet. The Ethernet communication layer between the RCU
and the distributed modules is functionally isolated from any point beyond the RCU so there is
no danger to having a remote host attempt to communicate directly with the hardware control
modules.
The COBRA RCP software is hardware independent through a software abstraction layer. This
allows easy transition to other vendors and products based on availability and features
In order to assure accurate and complete time stamping of each command, response, and status,
each module comprising the RCU is synchronized using the Network Time Protocol (NTP).
Additionally, filters and other integrity checks within the RCU and associated software elements
ensure that any command, response, error message, or status message is appropriately logged
and repeated entries are avoided.
1.1.1.2. COBRA HCI Module
The COBRA HCI software module operates at the gateway between the RCP module and the
EEC EDGE Radar Host computer.
1.1.1.3. COBRA LCI Module
The Local Control Interface (LCI) module is a computer based local control and operator interface
to the COBRA program functions. In this configuration, the LCI runs on the same computer as
the COBRA software. The user display shares the standard commercial keyboard and video
monitor unit with the IQ2-DSP and EDGE Host computer.
The software communicates with various radar components through the COBRA application
software in order to provide user commands to the system and reflect control and status data to
the user. Such data includes but is not limited to azimuth and elevation position, power levels,
and voltage/current measurements. The ability to monitor the radar performance over Ethernet
connections provides the flexibility and opportunity to monitor the radar from virtually anywhere.
LCI presents the radar control information as familiar indicators and controls on the computer
screen as a virtual control panel. Common indicator styles include the LED, round gauges and
seven-segment digital readouts. Some indicators switch views when clicked. Interaction is
through the keyboard and touch pad.
1.1.2. IQ2 Digital Signal Processor (Unit 1 A2)
The IQ2 DSP consists of a PCIe card in a high-performance Host Computer used for signal
processing deployed in the Control Cabinet. This design of the computer and PCIe card ensures
the highest performance available, as well as for flexibility in adapting to various radar system
configurations. The DSP receives digital I/Q over the high-speed optical link from the IQ2-IFD,
passes this data to the high-speed server for moments processing.
