In order to save the testing time, we test 4 AWR1642 Radar's RF performance in chamber at the same time.
Since the FWs (Profile configuration, Chirp configuration..etc) are the same, whether there will be mutual interference problems?
* We put 5 corner reflectors with RCS 1 in chamber.
* We check the received power (dBm) value for the PASS/FAIL condition.
* The 4 Radar's position is shown as below figure while testing. (Outside of chamber view, Inside of chamber with 5 corner reflectors)
The test environment is shown as follows:
* There are 5 corner reflector in the test chamber with RCS 1m square.
* The device under test (DUT) are 4 devices.
* There is no signal generator equipment to transmit Tx signal, we use AWR1642's TX to transmit the frame. The chirp settings are the same for these 4 devices.
* AWR1642 transmit the Tx and got the reflection signal from Rx, through ADC --> Range FFT --> Doppler FFT --> Angle FFT, we got the 5 corner reflector's range, power and angle.
* Then we check the power for these corner reflectors are within specification or not.
Since these 4 DUT tset at the same time, we are afraid that DUT1 might receive the DUT2's/DUT3's/DUT4's Tx signal and cause the problem.
