The AWR2544 is a single-chip mmWave sensor composed of a FMCW transceiver. The device is capable of operation in the 76 to 81GHz (EHF) band, includes radar data processing elements, and a rich set of peripherals for in-vehicle networking. AWR2544 provides customers with an additional Launch on package (LOP) antenna feature which facilitates the attachment of antennas directly on to the package. The AWR2544 is built with TI’s low-power 45nm RFCMOS process and enables unprecedented levels of integration in a small form factor and minimal BOM. The AWR2544 is designed for low-power, self-monitored, ultra-accurate radar systems in the automotive space.

TI’s low-power 45nm RFCMOS process enables a monolithic implementation of a 4 TX, 4 RX system with integrated PLL, VCO, mixer, and baseband ADC. The device includes a Radio Processor Subsystem (RSS), which is responsible for radar front-end configuration, control, and calibration. Within the Main Subsystem (MSS), the device implements a user-programmable Arm Cortex-R5F processor allowing for custom control and automotive interface applications. The hardware accelerator block (HWA 1.5) supplements the MSS by offloading common radar processing such as FFT, scaling, and compression. This saves MIPS on the external processor, opening up resources for custom applications and implementation of higher-level post-processing algorithms.

A Hardware Security Module (HSM) is also provisioned in the device (available for only secure part variants). The HSM consists of a programmable Arm Cortex-M4 core and the necessary infrastructure to provide a secure zone of operation within the device.

Simple programming model changes can enable a wide variety of sensor implementation (Short, Mid, Long) with the possibility of dynamic reconfiguration for implementing a multimode sensor.

TI has designed the AWR2544 specifically for satellite architecture. Satellite architecture adds value through a sensor fusion algorithm and the larger computing capability in the central ECU. Simplified satellite sensors and differentiation through software can help reduce system complexity and offer new ways of creating value.

Using satellite radars gives automakers the option to use over-the-air software updates to improve system performance and enhance security. These multiple benefits – performance, scalability and simplicity – all contribute the prominence of the satellite architecture in the automotive industry.

Additionally, the AWR2544 is provided as a complete platform including TI hardware and software reference designs, software drivers, sample configurations, API guides, and user documentation.

ZEN-3P-DARSW — Zendar 分散式孔徑雷達 | 具有相干感測器網路的高解析度雷達

Zendar 的分散式孔徑雷達 (DAR) 軟體融合了兩個或三個中程雷達 (MRR) 感測器，這些感測器協同工作以提供增強的雷達解析度。使用兩個實體位移的感測器建立一個大的虛擬孔徑，可以將方位角解析度提高到 0.5 度或更低，這有助於分離間隔很近的物體。車輛雷達解決方案受尺寸限制和安裝限制，而性能通常受感測器尺寸限制。分散式孔徑雷達系統可透過感測器的間距來擴大系統的孔徑，而不需要建造更大、更昂貴的硬體。分散式孔徑雷達採用模組化方式，可以在因應對汽車產業獨特的設計和整合挑戰方面發揮關鍵作用。DAR 以傳統雷達技術為基礎，結合多個標準感測器，打造出超越各部分性能總和的解決方案。
