原标题：大联大世平集团推出基于TI产品的车载短程雷达解决方案

　　致力于亚太地区市场的领先半导体元器件分销商---大联大控股宣布，其旗下世平推出基于德州仪器(TI)产品的车载短程雷达解决方案。该方案为使用AWR1642评估模版(EVM)应用提供了基础，帮助AWR1642在车辆周边环境建立3D高分辨率感知环境，实现系统从0到100米范围内的实时检测。

　　遍布车辆周身的雷达会随着车辆的不同状态而自动调整感知性能，比如当车辆慢速行驶时，其雷达可提供从几个厘米到十几米的感知环境;当车辆高速行驶时，其雷达的感知范围则会扩大到60-80米。配备了TIDEP-009的短距离雷达(SRR)解决方案的AWR1642方案就具有动态调整的配置，在AWR的设备上，它可以根据车辆的不同的状态，自动调整配置，感知范围随着车速的变化而扩大。

　　描述

　　The AWR1642 device is an integrated single-chip FMCW radar sensor capable of operation in the 76- to 81-GHz band. The device is built with TI’s low-power 45-nm RFCMOS process and enables unprecedented levels of integration in an extremely small form factor. The AWR1642 is an ideal solution for low-power, self-monitored, ultra-accurate radar systems in the automotive space.

　　The AWR1642 device is a self-contained FMCW radar sensor single-chip solution that simplifies the implementation of Automotive Radar sensors in the band of 76 to 81 GHz. It is built on TI’s low-power 45-nm RFCMOS process, which enables a monolithic implementation of a 2TX, 4RX system with built-in PLL and A2D converters. It integrates the DSP subsystem, which contains TI’s high-performance C674x DSP for the Radar Signal processing. The device includes an ARM R4F-based processor subsystem, which is responsible for radio configuration, control, and calibration. 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. Additionally, the device is provided as a complete platform solution including reference hardware design, software drivers, sample configurations, API guide, and user documentation.
