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 分布式孔径雷达 | 具有相干传感器网络的高分辨率雷达

Zendar 的分布式孔径雷达 (DAR) 软件将两个或三个协调运行的中距离雷达 (MRR) 传感器融合在一起，从而提供更高的雷达分辨率。使用两个物理位移的传感器可形成一个较大的虚拟孔径，从而提高 0.5 度或更低的方位角分辨率，这有助于分离彼此靠近的物体。车辆雷达解决方案受限于尺寸限制和安装限制，而性能通常受限于传感器的尺寸。分布式孔径雷达系统通过传感器间距来扩大系统的孔径，而不是构建更大、更昂贵的硬件。分布式孔径雷达具有模块化方法，可以在应对汽车行业独特的设计和集成挑战方面发挥关键作用。DAR 建立在传统雷达技术的基础上，结合多个标准传感器，从而打造一种性能优于各部分之和的解决方案。
