Antenna pattern interpolation
Antenna pattern interpolation
(OP)
What techniques exist to obtain an approximation of the 3D antenna pattern from the 2D (azimuth and elevation)pattern?
thanks

What about a visualization technique for 3D?

This is a good start but is still a linear interpolation process.

RE: Antenna pattern interpolation
If the antenna is relatively simple (and has a 'simple' pattern), then the best approach might be to model the antenna using NEC and then attempt to match the model to the provided cuts. In other words, use the provide cuts to calibrate the NEC model. The possibility exists that the NEC model will reveal that the provided cuts are not representative of the overall pattern.
Either way, the overall pattern should integrate (over the entire sphere) to something just under 0 dBi average gain (just under 100% efficiency) - a very useful final 'sanity check'.

Simulation would be the better option if the antenna dimensions and configuration were known.

Besides, for a simple antenna, you could easily use NEC to make a better prediction. www.eznec.com has a free demo that can handle 10 segments (enough for the simplest case). It is very easy to use.

For: Forward modeling is carried out for a multi-component 3D survey in which a buried point scatterer is
present. 3D imaging is carried out using this multi-component dataset for different source-receiver setups.
Using the finite bandwidth of the received signal and a limited aperture this 3D imaging scheme is efficiently implemented.
