Phased Array System Toolbox
Design and simulate phased array signal processing systems
Phased Array System Toolbox™ provides algorithms and apps for the design, simulation, and analysis of sensor array systems in radar, wireless communication, EW, sonar, and medical imaging applications. You can design phased array systems and analyze their performance under different scenarios using synthetic or acquired data. Toolbox apps let you explore the characteristics of sensor arrays and waveforms and perform link budget analysis. In-product examples provide a starting point for implementing a full range of phased array multifunction systems that require frequency, PRF, waveform, and beam pattern agility.
For radar, sonar, and EW system design, the toolbox lets you model dynamics and targets for ground-based, airborne, ship-borne, submarine, and automotive systems. It includes pulsed and continuous waveforms and signal processing algorithms for beamforming, matched filtering, direction of arrival (DOA) estimation, and target detection. The toolbox also includes models for transmitters and receivers, propagation channels, targets, jammers, and clutter.
For 5G, LTE, and WLAN wireless communications system design, the toolbox enables you to incorporate antenna arrays and beamforming algorithms into system-level simulation models. It includes capabilities for designing and analyzing array geometries and subarray configurations, and provides array processing algorithms for conventional and hybrid beamforming, DOA estimation, and spatial multiplexing.
