The W1905 Radar Model Library saves development time and verification expense in R&D for radar system architects, algorithm developers, and system verifiers.
The library provides approximately 90 highly-parameterized simulation blocks and several dozen ready-made reference designs for creating working radar system scenarios, including radar processing blocks, environmental effects items such as clutter, targets, and even hardware measurements. Instead of modeling an entire scenario from primitive function calls for each object, simply connect realistic reference designs with RF models and test equipment to study and verify radar system architectures. The W1905 library can be applied to a wide range of radar technologies, making it a useful algorithmic reference for both commercial and military applications.
The W1905 library recently added 3D inertial modeling “layers” above the baseband radar signal processing references(see Figure 4 below). They account for the 3-D positions, velocities, rotations, and beamforming directions of each transmitter, receiver and target, allowing modelers to create and script meaningful airborne, shipborne and multi-static scenarios or environments.
- pulsed and pulsed-doppler (PD) radar architectures for telemetry and EW applications
- ultra-wideband (UWB) radars, and wideband receivers
- phased array and digital array radars (DAR), with dynamic coordinates, attitude, and beamforming weights
- synthetic aperture radars (SAR) and beamforming for raster imaging and mapping
- stepped-frequency radars (SFR) for ground- and wall-penetrating applications
- frequency modulated continuous-wave (FMCW) radars for automotive applications
- MIMO radars for increased range resolution and robustness
- Multi-static radars with multiple TX and RX locations, which can be in motion (vehicle/ship/air/space-borne)
- signal generation for embedded simulators and test & measurement applications

The W1905 blockset and its example workspaces serve as algorithmic and architectural reference designs to verify radar performance under different signal conditions. These can include target and RCS scenarios, clutter conditions, jammers and environmental interferers, and more. 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 architectures with high confidence in early R&D, without requiring expensive outdoor range testing or hardware simulators.
SystemVue connects baseband algorithm modelers with a variety of other domains. SystemVue can also be used to create reference signals for download to test equipment, as well as post-process signals captured from test equipment, to create virtual verification systems at low cost.
Figure 1. SystemVue’s W1905 radar library helps model the signal processing algorithms as well as the radar environment, and connects to UWB test equipment, such as the new Keysight M8190A AWG, M9703A digitizer, and Keysight’s 90000-series oscilloscopes.
Recent Upgrades (as of SystemVue 2013.08 SP1)
- Now provides an inertial coordinate framework for modeling moving platforms, targets, clutter, and including the effect of dynamic RCS and beamforming patterns in 3-dimensions. This allows easier creation of multi-static airborne and ship-borne scenarios.
- New blocks and examples for MIMO Radar, Phased Array Radar with dynamic beamforming, Stepped-Frequency Radar (SFR), Synthetic Aperature Radar (SAR), Automotive Radar, electronic warfare (EW) and electronic counter measures (ECM)
- New and updated models for user-defined antenna patterns and scanning, clutter models, moving targets, polarization, time-gating, pulse compression, CFAR, Direction of Arrival, MUSIC, SPIRIT and other algorithms
- External scriptability and control of the SystemVue platform, allowing integration with other application providers, such as terrain map databases and structured verification suites
Updated instrument drivers for Keysight’s family of wideband arbitrary waveform generators (AWG), such as M8190A. SystemVue also includes a new waveform utility called “Waveform Sequence Composer”. Sources can also now include jitter and programmable pulse offsets.

Figure 2. The W1905 radar library calculates a SAR example with 2D pulse compression algorithms to reveal 5 actual targets. (3D plots were rendered by MATLAB, controlled from within the SystemVue simulation).
Figure 3. Fading, delay, and other parameters from a virtual flight scenario over a 3D terrain database were passed from the AGI STK 10 software into the fading, target and clutter models of the SystemVue W1905 radar library. SystemVue was then scripted to render the actual RF signal at any point along the virtual mission to Keysight instruments, in order to provide far less expensive “virtual flight testing” in an R&D environment.

Figure 4. The W1905 library now supports the creation of 3D scenarios with motion and rotation, along with adaptive digital beamforming (ADBF) for phased arrays, and electronic warfare (EW) techniques. These are essential tools for modeling realistic shipborne, airborne, and spaceborne systems.
