W1905 Radar Model Library - 1

SystemVue W1905 Radar Model Library Data Sheet Key Benets • Accelerates the Radar/EW modeling process using a model-based platform and multi-format IP integration • Reduces integration risk for RF-DSP architectures with earlier crossdomain analysis and verification • Validates algorithms and systems under realistic, complex scenarios • Saves time by starting from validated templates and block-level reference designs • Generates wideband Radar/ EW waveforms and scenarios using wideband test and measurement equipment, directly from simulations • Leverages user’s existing IP and test assets throughout the process Offering the Fastest Path from Radar/EW Design to Verication and Test The W1905 Radar Model Library is a simulation reference library for designing and testing Radar and electronic warfare (EW) systems. It is available as an option to the SystemVue system-level modeling software. Modern Radar and EW systems are incredibly complex. They employ complicated architectures with state-of-the-art technology from multiple engineering domains and are installed on a diverse array of platforms such as airplanes, satellites and ships to track, detect and identify a variety of potential targets. Additionally, they must work in a host of operational environments that can include interference, jamming/deception clutters and different target radar cross sections. To save development time and reduce cost, the SystemVue Radar Library provides 92 highlyparameterized simulation blocks and 93 higher-level reference design workspaces to create working Radar/EW system scenarios. These scenarios can include Radar and EW signal generation and processing, as well as environmental effects like clutter, jamming, interference, targets, and simulated platform and target hardware specific parameters. The ability to simulate not only a Radar/EW system concept, but the full deployment environment enables unprecedented development speed and provides rapid prototyping capabilities for any Radar/ EW system development. While the W1905 Radar Model Library is primarily structured for direct modeling and simulation of a conceptual Radar/EW system and its operational environment, it also can be used to design, verify and test development hardware. The W1905 block set and its example workspaces serve as algorithmic and architectural reference designs to verify Radar/EW performances under different signal conditions and environment scenarios. By accounting for a diverse set of environmental effects, while maintaining an open modeling environment (.m, C++, VHDL, test equipment), the Radar system designer can explore Radar/EW architectures with high confidence, rapidly test and prototype development hardware, and simulate operational results in multiple concept operations, without requiring expensive outdoor range testing or hardware simulators.

The "scenario framework" simulation technique can model any system, from sta- tionary monostatic ground-based systems to more complex multistatic and phased-array systems, including Multiple-Input Multiple- Output (MIMO) Radar. • The modeling framework supports motion of the Radar transmit and receive platforms, as well as multiple targets, in an earth-centered inertial (ECI) frame • Multiple antenna arrays can be setup in the framework for different systems • Sophisticated Radar/EW scenarios, together with complex target modelling, A simulation example using the scenario framework is shown...
