5.7.1 How Can FMCW Radars Be Used?

A FMCW radar uses chirps for the radar detection and ranging. A chirp is a sinosoid of linearly varying frequency. In mmWave sensors, users can configure the chirp as required to meet the system performance parameters like range, range resolution, maximum detectable velocity, field of view and so forth.

The Programming Chirp Parameters in TI Radar Devices application note provides information on how to select the right chirp parameters in a fast FMCW Radar device based on the end application and use case, and program them on TI’s radar devices.

The MIMO Radar application note introduces the basic principles of the MIMO radar and the different design possibilities. The document also provides an in depth explanation of the TDM-MIMO strategy.

Using the path shown below in the device specific MCU Plus SDK package, users can find an in depth explanation of the DDM-MIMO Strategy.

The Interference Mitigation on the AWR294x Transceiver application note describes the mechanisms of interference and methods to mitigate interference, using algorithms designed for and hardware hooks designed into the TI family of radar devices.
