The Radar Equation Calculator app estimates maximum range, peak power, and SNR of a radar system.
The Radar Waveform Analyzer app analyzes performance characteristics of pulsed, frequency modulated, and phase coded waveforms.
The Sensor Array Analyzer app analyzes beam pattern of linear, planar, and conformal sensor arrays.
Apps are interactive MATLAB programs you can use without writing any code. Most toolboxes come with apps, and you can download more for free from the MATLAB File Exchange. You can also package and share your own apps.
