| Abstract: |
| High-performance millimeter wave radar is widely used in the field of intelligent driving and intelligent automobile as an important detection and sensing component. The radar has high professional integration and is difficult to test. Starting from the design requirements of detection index and RF basic conditions，the realization and verification method of detection index based on radar target simulation is analyzed around theoretical calculation, design scheme and index verification. From the shielding performance of darkroom, the size calculation of darkroom and the simulation design of darkroom static zone performance, the formation process of RF basic conditions of test system is studied. The test system provides an effective means for improving the test and evaluation technology of high-performance millimeter wave radar and building a collaborative development of intelligent vehicle technology innovation system. |
