ADAS Testing Systems
ADAS validation moved into the chamber because you cannot drive every scenario on a test track. Over-the-air rigs and radar target simulators reproduce the world electronically — which means the RF chain feeding them has to be stable enough that a difference in the result is a difference in the vehicle, not in the cable.

Design Notes
What an OTA Rig Demands
Five properties that separate a usable ADAS test chain from a misleading one.
01
Run-to-Run Repeatability
Scenario testing compares one run against another. Anything in the RF chain that drifts between runs shows up as a vehicle behaviour change that never happened.
02
Long Chamber Runs
Instruments sit outside the chamber and horns sit inside. Those runs are long, and loss over them directly limits the dynamic range of the simulated target.
03
Cable Movement
Positioners move during a scenario. Cable that changes phase as it flexes injects an artefact directly into the angle measurement.
04
Multi-Channel Matching
Multiple horns simulating multiple targets have to be matched to each other, or the geometry the vehicle perceives is wrong.
05
Duty Cycle
Validation benches run continuously. Connector wear is a scheduled maintenance item, and cycle life sets the schedule.
Reference Data
Typical OTA Rig Requirements
Rig requirements vary by supplier and scenario set. These are representative.
| Parameter | Typical Requirement | Relevant Series | Note |
|---|---|---|---|
| Frequency | To 110 GHz | 1.0mm, CFT series | Radar and comms bands |
| Chamber run loss | As low as practical | Low-loss test cable | Sets target dynamic range |
| Phase stability, flexure | ±3° typical | Phase-stable series | Positioner movement |
| Channel matching | Matched set | Matched assemblies | Multi-target geometry |
| Mating cycles | 5,000+ | NMD-terminated | Continuous duty |
| Calibration | Measured data supplied | All test assemblies | Per unit |
Our Role
What We Supply for ADAS Rigs
01
Chamber-Length Assemblies
Low-loss runs built to the actual instrument-to-horn distance, so the target dynamic range is not spent on cable.
02
Matched Channel Sets
Multi-channel assemblies supplied as a matched set with measured data, so simulated geometry is trustworthy.
03
Documented Performance
Per-unit measured data and traceability, which validation reporting requires as evidence.
