Part Number: TDA2SX
Other Parts Discussed in Thread: TDA2

Using the TDA2 Cascade EVM, our custom front end has non-half-lambda antenna offset.

In PROCESSOR_SDK_VISION_03_07_00_00\vision_sdk\docs\Radar\ProcessorSDKRadar_DataSheet.pdf -

"3.9.1.6.3 Understanding Antenna Offsets in the board":

*Here the antAzimOffs and the antElevOffs are given in half lambda spacing convention*

How do we manage antenna offset in our front end where the offset distance divided by Lambda/2 are fractional not whole number?

I would need to consult with radar experts here to help you. I will forward the question and get back to you.

Thanks and Regards,

Hello Zach,

For non lambda/2 by two spacing the processing would have to be very customized based on the exact antenna configuration you have. Could you provide the reasoning for using non lambda/2 multiple spacing? Also can you provide the exact antenna pattern?
