RVP - Radar Video ProcessorA family of solutions for primary radar video distribution, plot extraction and target tracking RVP - Radar Video Processor - is Curtiss-Wright Controls Embedded Computings' family of high-performance radar acquisition, tracking and distribution servers that are designed to address a broad range of radar processing requirements from network radar video servers to ruggedized naval tracking solutions. RVP servers are designed to work with Curtiss-Wrights' extensive range of radar client solutions for video and track display. Alternatively they may be used in standalone configurations providing, for example, radar plot extraction and tracking data into an existing display or fusion system. Curtiss-Wright has a unique range of capabilities in the field of radar acquisition, display, distribution and tracking, and has successful installations world-wide in a diverse range of market sectors. These include air traffic control, vessel traffic systems, aircraft ground-movement, coastal surveillance and naval tracking systems. Representing the latest generation of product offering, RVP builds on expertise in over 15 years of radar tracking installations, and exploits the latest advances in networking and high-performance processing to provide highly cost-effective COTS solutions to radar distribution and tracking requirements. The RVP product family spans a range of capabilities from radar video servers through to full auto-tracking solutions for naval, air traffic control and vessel traffic applications. Based on proven solutions for radar acquisition and processing, RVP builds on our experience in offering integrated and OEM-level solutions that meet demanding requirements. Modular software design and open-systems hardware allows a rich set of capabilities to be provided in a compact and cost-effective form-factor built on standard COTS hardware platforms. At the heart of RVP is a set of integrated software modules that provide radar processing capabilities. These software modules are designed to work on industry-standard operating systems and computing platforms, ensuring that systems can be upgraded and maintained over their operating life. RVP software modules provide the following capabilities:
RVP Tracker Architecture RVP Radar AcquisitionRVP receives radar video from our radar input card, for example Virgo for PCI bus and Osprey for PMC. Radar turning signals and analogue or digital video is received by the radar input card and processed to generate integrated digital data for subsequent analysis. An extensive range of radar input types are supported, including ACP/ARP, syncho, RADDS, ASDE-3 and various parallel and serial azimuth formats. RVP Radar Processing RVP Radar Video Compression The RVP Video Distribution module accepts the RACE coded polar-format radar video and distributes it across a network. Standard IP protocols are used to package the coded video for delivery to single (unicast) or multiple (multicast) workstations. It is significant that the network bandwidth utilised by the distribution depends only on the radar video and the selected compression ratio and not on the number of connected workstations. RVP Radar Recording RVP Plot Extraction RVP Tracking Tracks are created either through manual initiation from an external system, or through automatic initiation from the tracker itself, and are maintained in an active track database. Each rotation of the radar creates a new set of plot data which is used to update entries in the database and estimate filtered position, speed and accelerations of the target. Typically there are far more plots generated than targets maintained, so one responsibility of the RVP Tracking module is to select the appropriate plots to match with the entries in the track database. Plots that remain after this matching process are potentially new targets, and may be initiated as new tracks if they pass acceptance rules on their motion. Updated track data is reported on the network in the form of a track report. RVP Local Display The RVP Remote Control Interface supports network-based control of an RVP system. A complete command interpreter is provided to allow full remote control of all aspects of the operation of the system, including distribution, plot extraction, tracking and radar recording, according to the installed options. The control protocol is based on simple ASCII command strings, which are packaged into UDP datagrams according to our standard message-passing protocol. It is straightforward to write software to send commands to RVP and sample code is provided with the RVP release to show how to do this from Unix or Windows-based clients. RVP Systems Configurations For each of these baseline configurations, options exist for both packaging and functional enhancements to provide additional capabilities for radar video recording and display.
