ARENA Technology 

Remote Sensing Solutions, Inc (RSS) is proud to offer its patent pending ARENA product line. The ARENA modules are adaptable, reconfigurable and modular digital sub-system solutions for waveform generation; digital receiver & signal processing; timing & control signal generation and reception; and data acquisition & distribution. Figure 1 shows a photograph of an ARENA 103 and ARENA 313 module (top) and an ARENA 313 module (bottom) configured as a dual-channel software defined radar supporting signal frequencies up to 2 GHz with 600 MHz of bandwidth, providing multi-subchannel, match filter and covariance processing and data communications up to 20 Gbps while consuming only 20 W.

RSS ARENA technology can transform a radar, sonar or radiometer by enabling significant miniaturization; unparalleled processing; adaptive control, waveform generation and signal processing; and seamless integration into network sensor environments. With its intra-module synchronization interface, each ARENA can be phase locked to a reference clock and multiple ARENAs can be combined and phase synchronized on a pulse-to-pulse based to solve complex problems (e.g., active & passive phased arrays) with state-of-the-art phase alignment that meets the most demanding needs.   Its unique architecture encapsulates each function that an ARENA implements into an object at the hardware, firmware and software layers, and these objects are configured and controlled through their eXtensible Markup Language (XML) objects. Simply modifying the XML objects, rather than firmware and/or software, the functions can be modified, turn on and off and their data shared.  This provides a “plug and play” solution that simplifies integration and operation and allows for optimization and adaptation even on a pulse to pulse basis. Physically not much larger than a smart phone, ARENA(s) can be embedded into the sensors they serve. ARENA modules weigh less than a pound and consume only 5W to 25W of power depending on their mezzanine cards and run-time configurations. Reconfigurable at the hardware, firmware and software levels and adaptable on a pulse-to-pulse basis (even within a pulse), an ARENA based solution can be optimized to each system and even within a mission.
