How to Validate Short-Range Automotive Radar Detection

+ Radar Scene Emulator

Exercise Radar Detection at Short Distances

Short-range radar validation requires controlled target distance, angle, velocity, and reflection level close to the radar sensor. Engineers configure stationary and moving objects within the near-field test region, then exercise the advanced driver-assistance system (ADAS) radar while monitoring target detection, range estimation, and track initiation. A radar scene emulator presents repeatable objects at distances as close as 1.5 meters so close-in detection behavior can be evaluated without moving physical targets.

The same scene is repeated while target distance, angular position, velocity, and spacing are varied systematically. Engineers compare reported range, angle of arrival, detection state, and track behavior with the programmed scene as targets enter, remain within, and leave the short-range region. Repeatable scene generation makes it possible to isolate threshold behavior and separation performance while keeping the radio-frequency environment and target geometry consistent between runs.

Short-Range Automotive Radar Validation Solution

To perform the test, engineers must present stationary and moving radar targets at controlled short distances, angles, and velocities. The Keysight Radar Scene Emulator generates repeatable automotive radar scenes with targets as close as 1.5 meters, supporting evaluation of detection, range estimation, angular response, and track initiation near the sensor. Engineers can vary target spacing and motion without repositioning physical reflectors, then repeat the same scenario across software or sensor revisions. The solution supports full-scene generation across a contiguous field of view and can combine close-range objects with more distant targets to exercise perception behavior under realistic driving conditions.
