Range and Doppler Estimation

Range estimation, range-Doppler processing, and FMCW range estimation.

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.

Overview of Basic Workflow

This section provides an introduction to the end-to-end radar simulation.

End-to-End Radar System

The basic toolbox workflow is applied to a monostatic radar system consisting of a single antenna.
