Virtual Development and Test Environment


CDSI has developed the Virtual Development and Test Environment (VDTE) to allow an improved approach to radar development and operational system support.  The VDTE based on the principles of simulation-based design and emulation-based operation, allowing it to be used before and during deployment in the field.It was developed initially for use with the Firefinder Radar (which is fielded all over the world), and is being considered for other radar deployments.

The VDTE can simulate any engagement scenario in the radar's operational environment, and emulates the actual radar code in order to investigate the radar's behavior in this engagement. This allows observation of the radar performance envelope, and rapid identification and resolution of problems found for engagements of interest -- particularly those arising from situations encountered in the field.  This function has proven indispensible for finding the root cause of undesired behavior in new deployments, and shortening the cycle time of mitigating such problems and significantly reducing the cost of deploying updates.

The VDTE simulation environment draws from a large database of phenomenology, maintained by the Government and applicable to almost any type of radar engagement. The (separate) emulation environment is based on the actual radar operational code, and inserts virtual instruments to provide excellent visibility into the interactions between the (emulated) Radar and its (simulated) environment, all taking place on the developer's desktop, where problems can be reproducibly investigated and resolved before tying up valuable hardware assets, thus assisting the entire Project management chain.  It is also able to process recorded data from field testing, and compare the results with what would be expected from simulation/emulation within the VDTE (see before/after pictures taken from actual field-test data).

The VDTE allows developers to resolve problems in a laboratory environment while emulating engagements either observed or anticipated the field, even those that cannot be created live for radar field testing due to issues of safety, cost, or unavailability of the right combination of assets.
