AWR2944P

The AWR2944P is a highly integrated radar sensor from Texas Instruments designed for high-resolution, short-range sensing applications. It operates in the 76–81 GHz frequency band, enabling precise detection and tracking of objects with exceptional accuracy. The device integrates a complete transceiver system on a single chip, including multiple transmit and receive channels, digital signal processing (DSP), and microcontroller units (MCUs), which significantly reduces external component count and board space requirements. This radar sensor features advanced beamforming capabilities through its 4T4R (four transmit, four receive) architecture, allowing it to form narrow beams for improved angular resolution and clutter rejection. It supports up to 512 virtual antennas via chirp sequencing, enhancing range and velocity resolution for complex environments such as automotive cabins or industrial automation systems. The AWR2944P also includes on-chip calibration and self-diagnostics, ensuring consistent performance over temperature and time without additional software overhead. Key functionalities include Doppler-based motion detection, distance measurement, and object classification using AI-enabled signal processing. Its low power consumption—under 1.5 W during active operation—makes it ideal for battery-powered or energy-constrained applications. The device supports both continuous wave (CW) and frequency-modulated continuous wave (FMCW) modes, offering flexibility in application-specific configurations. Designed for automotive and industrial use cases, the AWR2944P excels in occupancy detection, blind-spot monitoring, and driver attention systems in vehicles. In industrial settings, it enables automated door control, machine safety, and personnel presence detection in hazardous zones. It also supports smart home and IoT applications such as gesture recognition and occupancy sensing in HVAC systems. The AWR2944P comes with a comprehensive development ecosystem, including TI’s SimpleLink™ SDK, reference designs, and evaluation modules like the AWR2944P EVM, accelerating prototyping and deployment. Its robust RF performance, combined with embedded intelligence and scalable integration, positions it as a leading solution for next-generation radar sensing across diverse markets.
