摘要： 汽车雷达是汽车智能辅助系统（ADAS) 中检测目标物的核心传感器。雷达截面（RCS）是评估
汽车雷达性能的重要参数。该文根据雷达截面测试与标定原理，提出了一种用于雷达测试、代替行人
的标准物标。以长度1 m、雷达截面0 dB 以下的圆管为小物标，测试了雷达截面；分析了不同圆管的
材料特性、尺寸、形状、倾斜角度等对雷达截面的影响；评价了各种测试物标对电波的反射和吸收特性。
结果表明：使用该标准物标更易于测试ADAS 系统的性能，可提高雷达对行人的检测能力。

Abstract: Automotive radar is a kind of key sensor for the range detection of objects in Advanced Driver
Assistance Systems (ADAS) such as the pre-crash system and the backing aid system. Radar cross section
(RCS) was measured as an important reference data to evaluate and compare the radar’s performances. After
analyzed methods of measuring and calibrating RCS, a standard object was developed to represent pedestrian
in vehicle radar performance tests. The RCS was measured for small targets (such as a pipe) with length of
1 m and RCS below 0 dB to analyze the influence of different characteristics of pipe such as the material,
diameter, and inclination angle on the RCS. Radio wave reflection and absorption properties of test objects
were evaluated as well. The results show that by setting up a standard object of pedestrians, it is easier to test
performance of any ADAS application system, therefore, improving radar’s ability to detect pedestrians.

Key words: vehicle safety, automotive radar, advanced driver assistance systems (ADAS), radar cross section (RCS), pedestrian, standard object, measurement and calibration system
