Introduction

Offering the Fastest Path from Radar/EW Design to Verification 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 stateof- 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 110 highly-parameterized simulation blocks and 90 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 (MATLAB, 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. 

Key benefits

- 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 cross-domain 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

New Simulation Approach

The “scenario framework” simulation technique can model any system, from stationary 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, are supported

Trajectory layer (shaded light green) – Locates all transmitters, receivers and targets in 3D position, velocity and acceleration spaces.

Antenna layer (shaded yellow) – Tracks rotational attitude (pitch, yaw, roll) and beamforming directions for antennas and phased arrays. Phased arrays are true arrays.

Signal layer (shaded green) – Traditional baseband signal processing paths, which can include MATLAB, C++, HDL, and RF models, as well as W1905 blocks and instrument links.

Supported applications

The W1905 Radar Model Library includes over 90 examples that can be used as design templates and reference designs. Instead of starting from scratch, users can modify these block-level systems to reflect their algorithms, environments and measurements.

Applications for the W1905 library

- Create proposals and assess feasibility quickly

- Accurate Radar system architecture and scenario analysis

- Algorithmic reference and test vector generation for baseband DSP hardware design

- Precisely-degraded baseband/RF signal generation for receiver testing

- Radar/EW test signal generation, processing and analysis

- Include realistic RF effects, clutter, RCS, and directly-measured target returned waveforms

- Leverage existing math, HDL, and C++ algorithms

- Continue into hardware test using the same SystemVue environment and IP

- 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 Keysight simulation tools and test equipment
