Description

SystemVue ESL Design SoftwareThe 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.

Radar Technologies

  • 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. 

SystemVue Radar Models

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 Agilent M8190A AWG, M9703A digitizer, and Agilent’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 Agilent’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.

Who should buy the W1905 Radar Model Library?

  • Radar system designers in military, regulatory, commercial, avionics, automotive, medical, research, academic, and consulting applications.
  • Electronic Warfare system architects developing can use the W1905 as a working reference IP to model unfriendly radar topologies for jamming and countermeasure scenarios

Applications:

  • Create proposals and assess feasibility quickly
  • Accurate radar system architecture and scenario analysis
    • Include realistic RF effects, clutter, fading, and directly-measured waveforms
    • Leverage your existing math, HDL, and C++ algorithms
    • Continue into hardware test using the same SystemVue environment and IP
    • Multi-Emitter Environment Test Signals
  • Algorithmic reference & test vector generation for baseband DSP hardware design
  • Precisely-degraded BB/RF signal generation for receiver testing
    • Reduce the need for expensive chambers, hardware emulators, faders, and field testing in the early phases of design
    • Reduce NRE and scripting with regression suites of simulated scenarios
    • Save time by verifying algorithms prior to targeted FPGA/ASIC implementation
  • Minimize project costs with easily reconfigured Agilent simulation tools and test equipment

SystemVue Radar Signal Path ModelsFigure 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 Agilent instruments, in order to provide far less expensive “virtual flight testing” in an R&D environment.

W1905 supports 3D scenarios with motion and rotation

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.
