Range and Doppler Estimation

Range and Doppler estimation, range-Doppler and range-angle processing, and FMCW range estimation, detection clustering

The Phased Array System Toolbox™ includes a System object and Simulink^® block for range-Doppler processing. Utility functions let you compute range-Doppler coupling, convert beat-to-range.
