Phased Array System Toolbox provides narrowband and broadband digital beamforming algorithms. It enables you to suppress interferences and avoid self-nulling with adaptive beamformers, such as minimum variance distortionless response (MVDR) and linearly constrained minimum variance (LCMV) beamformers. You can use STAP techniques to remove clutter and jammer. The system toolbox lets you beamform in a region of interest to estimate the direction of arrival (DOA) of incident signals for any array geometry. Alternatively, you can use efficient sum-and-difference monopulse trackers for a uniform linear (ULA) or rectangular array (URA) and super resolution techniques such as MUSIC and ESPRIT.
Phased Array System Toolbox provides common waveforms used in active sensor array systems. You can define the parameters of constant frequency (PCW), frequency modulated continuous wave (FMCW), and multiple frequency-shift keying (MFSK) continuous waveforms. The system toolbox lets you specify pulse repetition frequency (PRF), pulse duration, and bandwidth of linear frequency modulation (LFM), stepped FM, and phased coded pulse waveforms. You can also use Phased Array System Toolbox to analyze spectral properties, range resolution, Doppler resolution, and the coupling between range and Doppler.
Phased Array System Toolbox lets you model and analyze the behavior of active or passive electronically scanned arrays (AESA or PESA) with arbitrary geometries including uniform linear array (ULA), uniform circular array (UCA), and uniform rectangular array (URA). You can define your own array geometry by specifying the position and orientation of each element in 3D space. You can model common antenna and microphone elements whose radiation pattern can be described by an analytic function or defined by frequency-dependent measured data. The system toolbox lets you model array perturbations and mutual coupling between elements, specify polarization, define subarrays, and model heterogeneous arrays with multiple element patterns.
Phased Array System Toolbox provides matched filtering and stretch processing pulse compression, coherent and noncoherent pulse integration, range and Doppler estimation, and constant false alarm rate (CFAR) detection algorithms. You can use these algorithms to compute and visualize receiver operating characteristic (ROC) curves for various signal-to-noise ratio (SNR) levels or probabilities of false alarm. You can also determine the maximum target range and visualize radar vertical coverage on Blake charts.
Phased Array System Toolbox provides models for polarized point target reflectors defined by the radar cross section (RCS). You can create collections of distributed point reflectors for complex, distributed targets. By specifying position and velocity, you can model target trajectories. The system toolbox also enables you to model the free space propagation of signals including range-dependent time delay, phase shift, Doppler shift, and attenuation, along with clutter and jammer interferences. You can define complex scenarios and analyze behavior of end-to-end systems.
