I would like to know if a radar sensor (chrome flesh pg. 81) is considered a sensor function that could be housed in a cyberlimb, as per the rules in core 445-446.

It has capacity so yes it can be installed in things that take capacity.  GMs are free to restrict what a particular item can be installed in as there is no RAW.  It would be a huge mess to try and spell out what can get installed where so it's left to the GMs. 

[Novocrane]

I would say no. It's not described as a Sensor Function in Chrome Flesh, which is the necessary term to be included as part of a Sensor Array or Single Sensor.

[Hobbes]

It's headware, I'd let it be installed in a Cyberskull too.  Cyberarm, I'm not keen on, your GM's Mileage may vary.

If installed in a cyberlimb you'd need to adjust the 3D map in relation to your head, constantly keeping track of your cyberlimb and your head either through gyroscopes or RFID tags. Probably both. I'd probably rule that it takes up an extra point of capacity if installed in a limb.
