    HIGHLIGHTS

    PathWave System Design适用于 SystemVue 组件的 W1725EP 射线追踪设计套件包含两个部分:一个是单独的 GUI 软件,可从 SystemVue 调用;另一个是射线追踪引擎,嵌入在 SystemVue 中。它适用于对车载雷达的复杂使用场景进行建模。

    用户可以得到的好处是能够建立车载雷达场景的模型,并且准确性比以前显著提高。随着成像雷达的问世,这种增强的准确性对于验证关键任务型功能和性能尤其重要。

    自动驾驶汽车(AV)和先进驾驶员辅助系统(ADAS)面临着日益高涨的市场需求,这一趋势促使车载雷达解决方案呈现出飞速发展的态势。新频段和新类型的雷达信号不断涌现,不仅改变着这种安全技术的功能,同时也对开发人员掌控日益复杂的雷达信号处理任务提出了挑战。为了验证雷达算法的性能,必须在许多不同的复杂场景中对设计进行全面测试。公司纷纷采用仿真方法来帮助其在设计周期中更早验证设计,避免进行复杂且成本高昂的实际测试。

    解决方案详解

    射线追踪是一种使用射线光学探测雷达反射信号的方法。它能够对许多目标的反射信号建立模型,表现真实的场景。单一用户界面使设计人员可以用现有的模型库(包括车辆、行人和路边固定目标)替代这些模型,创建环境场景。一旦确定了雷达发射机的位置,这个引擎将计算场景中所有目标的信号反射,然后将得到的结果发送给 SystemVue 供目标分析仿真使用。

    PathWave System Design Ray Tracing Design Kit图 1. PathWave 系统设计软件的射线追踪设计套件。

    PathWave 系统设计软件(SystemVue)中的车载雷达程序库可以与 SystemVue 的其他全方位系统仿真功能结合使用,协同开发关键任务型且重视安全的复杂场景。这些场景可以用于验证领先的车载雷达设计。它可以帮助汽车设计师在有限的预算和时间内设计和验证方向角(DOA)和相位比较等算法。

    车载雷达库中提供有多散点目标参数化仿真模型,可以实现并显示目标上的微多普勒效应。这个模型库还能够导入天线方向图文件,用于地面杂波仿真。

    在将 SystemVue 连接到测试和测量仪器后,用户可在原理图工作区中添加输入和/或输出端口,从而可以导入和导出 IQ 数据文件,使得从仿真到试验和原型制造的产品开发周期大大缩短。

    给整个汽车生态系统中的设计人员带来的好处

    • 芯片设计人员可以验证设计在复杂参考场景中的性能
    • 设备厂商可以评测各家公司提供的芯片产品
    • 基带设计人员可以测试算法在实际配置中的性能
    • 轿车制造商和 OEM 可以对传感器融合/虚拟路测仿真中使用的特定场景进行“深入”分析

    产品信息

    这种射线追踪技术是 2020 版本 Pathwave 系统设计软件(SystemVue)的新增功能。通过与 SystemVue 现有的车载雷达模型库和射频系统建模功能结合使用,它可以为车载雷达设计人员提供完整的系统设计与验证平台。
