Radar Development Challenges


The table below shows some of the challenges that radar development presents and the benefits of the FishEye Software VREX front-end simulator.

Not Enough Testing in the Lab?

Development and testing of the front-end and back-end of a radar system must be performed separately, so that much of the high fidelity testing cannot occur until integration, often at the operational site. VREX allows high fidelity integration testing with the back-end in the lab environment.

Limited Simulation Capabilities?

Testing with the actual front-end hardware at the factory or on-site is necessarily limited to targets of opportunity or simple simulated targets due to the real-world physical constraints that exist. VREX is capable of generating tens of thousands of targets with high-fidelity, thus allowing much more extensive testing of the system than would otherwise be possible.

Expensive and Difficult to Upgrade Proprietary Simulation Hardware?

Where simulators are currently used, they are customized and unique to the sensor they are developed with. They are limited in scope because they are expensive to develop and do not have the leverage of a large installed base of users. VREX runs on off-the-shelf computers so that it can take advantage of new technology for upgrades, expansion and/or technology refresh to increase performance and extend the lifecycle for minimal cost. It is in use across a number of programs and radar systems, thereby allowing each of the programs to take advantage of the ever-increasing features and quality of the software.

Project Specific Simulation?

Where simulators are currently used, they are customized and unique to the sensor they are developed with. VREX is configurable so that a single framework can support multiple systems. The configuration is accomplished through text-based files and can be readily modified as new features, waveforms, or other updates are added to the sensor capabilities.

Long Development Time or Large Expense

Currently, development of a front-end simulator is an expensive proposition and its schedule is likely in the critical path and potentially too late to be used before integration. VREX is available today with full features and is fully configurable for specific radars. The configuration effort is much simpler and faster than developing a new simulator from scratch, thus making it possible to complete the simulation and use it during back-end development and prior to actual hardware integration.

Flight and Site Testing is Expensive, Impractical, Impossible?

Testing the radar back-end in flight, at sea, at a remote site, or wherever it is deployed, ties up the entire system and the entire support team. The expense of such testing, the limited availability of the test range, and the limited set of targets that can be tested against make it impractical or impossible to fully test the integrated system. VREX allows this testing to occur in the lab with a rich target environment that is fully configurable or can be supplied by an external target generation simulator. This allows more comprehensive testing to occur in a substantially less expensive environment. Further, this testing can be conducted well before the hardware is actually deployed to a test or operational site. This same cost savings can occur later as updates, upgrades, waveform changes, technology refresh, or other system maturation and maintenance activities are conducted.
