Increased support for wireless and radar design in Matlab/ Simulink environment

March 26, 2013 // By Nick Flaherty
MathWorks has strengthened support for wireless communications and radar design in its MATLAB and Simulink tools.

Release 2013a (R2013a) enhancements to the Phased Array System Toolbox helps users to model an end-to-end phased array system or process acquired radar data by using new capabilities for polarisation, array perturbations, and broadband arrays. SimRF includes a new circuit envelope solver to accelerate simulation and model load time; it also expands its library of components for the simulation of RF front ends at the system level. These enhancements help radar and communications system designers to model increasingly complex scenarios with greater accuracy and performance.

The major update to Phased Array System Toolbox includes monostatic and multistatic radar system modeling, including point targets, free-space propagation, surface clutter, and barrage jammer to help estimate maximum range, peak power, and SNR of a radar system. There is also improved modeling of sensor arrays and subarrays with arbitrary geometries for beam pattern analysis of linear, planar, and conformal sensor arrays, polarisation and platform motion specification for arrays and targets and GPU support to accelerate clutter modeling.

Enhancements to SimRF include faster circuit envelope simulation of multiple carrier-frequency models for arbitrary architectures. Combined with equivalent baseband technology for discrete-time simulation of single-carrier cascaded systems, this enables rapid RF modeling and simulation at the system level. Reduced simulation startup time and easier setup of circuit envelope simulation with enhanced configuration block, including unlimited number of simulation frequencies and automatic selection of fundamental tones, are intended to make design times shorter, helped by new models for active and passive components (amplifier, mixer, LC ladder, transformer, noise) and custom SimRF model authoring using the Simscape language.

“We rely heavily on MATLAB to design and model phased array performance in RADAR and communication markets,” said Robert Liechty, business development manager at Cobham Defense Electronics in the UK. “Phased Array System Toolbox has helped us rapidly measure and analyse antenna beam patterns with beam steering to evaluate our design performance. We are pleased to see major enhancements in Release
