dB Stimulator (dBSTM)
dBSTM is the core product for providing real-time computational responses from a cluster of compute nodes. This product uses common library functions whenever it supports the real-time processing to ensure consistency (i.e. gravity models are available and consistent across all tools). The products scheduling and modeling components are separated by a modular design to allow flexibility in applying to new problem domains. dBSTM uses IP to communicate, but is designed to operate over high-speed Infiniband fabrics. The product scales to arbitrary numbers of nodes and runs on a variety of available hardware. This product is currently used for radar stimulation (target & environment radar injection) and radar signal processing.
The dBSTM stimulation capability for BMDS radars employs distributed computing cluster technology. It allows fielding at software integration labs and tactical site locations while providing inherent support to concurrent and sim-over-live capabilities. The design maintains tactical message format to signal and data processors and minimizes sensor-specific deployment costs. Using the dBSTM design, new radars require only limited interface specification and development. The scenario handling capabilities of dBSTM include:
- Up to 1000's of targets per scenario; 100's of targets per beam
- Multiple bandwidths
- High fidelity wideband RCS signatures
- Detailed 6DOF mission trajectories (position and orientation)
- Complex and extended targets
- Complete environment characterization
- Rain, ionosphere, troposphere, etc.
