Fluid-Level Sensing Using 77-GHz millimeter Wave

The IWR1443 millimeter wave (mmWave) sensor is a highly integrated 77-GHz radar device that serves as a single-chip CMOS mmWave sensor solution suitable for proximity sensing, entry-level industrial radar applications and ultra-high-accuracy range measurements.
The sensor includes the entire millimeter-wave (mmWave) radio-frequency (RF) and analog baseband signal chain for up to three transmitters and four receivers, as well as a customer-programmable microcontroller (MCU) and hardware accelerator for radar signal processing.

This white paper covers the high-level architecture and features present in the device. It highlights a platform using TI’s family of low-power industrial MSP430 MCUs or SimpleLink MSP432 MCUs and IWR1443 mmWave sensors to meet the power and interface requirements for legacy industrial sensors. It also discusses some chirp-configuration examples illustrating a typical level-sensing application.
