// Key Features

MATLAB-Native Radar Simulation

The same physics engine as RadarSimPy — now in a MATLAB workflow.

Radar Modeling

Transceiver modeling with multiple Tx/Rx channels
Arbitrary waveform — CW, FMCW, PMCW, Pulse, and custom
Phase noise modeling
Phase/amplitude modulation — CDM, FDM, DDM, TDM
Fast-time & slow-time modulation

Simulation

Baseband data from point targets
Baseband data from 3D modeled objects & environments (ray tracing)
Interference simulation

// RadarSimPy vs RadarSimM
