Detection is an important part of a radar or sonar system. To improve detection capabilities, the Phased Array System Toolbox™ includes System objects for performing matched filtering and stretch-processing pulse compression, coherent and noncoherent pulse integration, range and Doppler estimation and constant false alarm rate (CFAR) detection for one or two dimensions. 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. You can plot radar coverage using Blake charts. Many function support both radar and sonar systems. You can determine the maximum target detection range using the radar equation or sonar equation.
