The Phased Array System Toolbox™ includes System objects and Simulink® blocks for performing matched filtering, constant false alarm rate (CFAR) detection in one or two dimensions, stretch-processing pulse compression and coherent and noncoherent pulse integration. Utility functions let you compute and visualize receiver operating characteristic (ROC) curves for various signal-to-noise ratio (SNR) levels or probabilities of false alarm. Some utilities let determine the maximum target detection range. Others let you visualize radar coverage using Blake charts.

In phased-array applications, you sometimes need to decide between two competing hypotheses to determine the reality underlying the data the array receives.
Receiver operating characteristic (ROC) curves describe a detector's performance by relating probability of false alarm to probability of detection.
Generate an ROC curve using a Monte-Carlo simulation.
Matched filtering increases SNR and improves detection.

CFAR detectors apply the Neyman-Pearson criterion to target detection. The detectors estimate noise statistics from data.
