ARENA

The ARENA is a patent pending radar digital subsystem solution that offers a modular approach which is reconfigurable at all levels: hardware, firmware and software. It is reconfigurable (adaptive) on a pulse-to-pulse basis enabling real-time optimization to support cognitive sampling and processing solutions. Through multiple plugin modules (mezzanine cards), an ARENA can provide a radar with:

• Control & timing signals

• General data acquisition and system monitoring

• Arbitrary waveform generation

• Complex digital receiver, filtering & signal processing

• Data distribution & storage

The ARENA is implemented with a novel object-oriented and network centric system architecture. Every function at the hardware, firmware and software level is encapsulated into individual objects. Each object reports who it is, what it needs and what it provides. This enables each ARENA and the full system (up through the graphical user interfaces and displays) to automatically self-build. Each object’s configuration and data are captured by eXtensible Markup Language (XML) objects enabling the user or system to configure and reconfigure every object within each ARENA through simple manipulation of these XML objects. The ARENA network centric architecture treats each object as a node on the network providing serial and parallel data flow of an object’s data simultaneously, which allows an ARENA-based approach to meet a very wide range of needs and also to be easily customized for optimal performance for each radar, for each deployment and even on a pulse-to-pulse basis. Through the ARENA’s intra-module synchronization interface, each ARENA can be phased locked to a reference clock and multiple ARENAs can be combined and synchronized to solve complex problems with state-of –the-art phase alignment that meets the most demanding requirements.

With an ARENA-based digital subsystem solution, a radar becomes a node on a network facilitating remote operations and enabling a radar system to seamlessly join a sensor network. All data communication with the ARENA(s) is achieved through standard network socket communications making interfacing with other systems straight forward regardless of their operating systems. the ARENA-based solution compatible with wide range of operating systems. Secure/encrypted data communications using standard protocols can also be achieved.

The ARENA provides a full solution rather than just hardware. Each ARENA plugin module (mezzanine card) corresponding firmware module is broken down into encapsulated objects and can be configured on-the-fly to implement a broad range of functions simply through its XML configuration objects.
