antenna time domain measurements

Hello,

Can somebody provide information of time domain antenna raddiation pattern measurements?.

I do not mean time gating to remove particular reflection directions, but complete radiation pattern measurements in the time domain. I have just got a paper on the topic and it seems very interesting.

thanks

Hi dowjones

This kind of measurements mostly used in near field you measure the
antenna with pulse then you transform to frequency domain and you get
from it. the measurements, of the all frequency band. instead of sweeping the frequency during the scan.

OK,

then in an spherical range how do you get the full (theta,phi) radiation pattern? Is it possible?.

What I want to know is whether it is possible to measure in theta-phi with this pulsed/time domain method and get the complete spherical pattern in a complete frequency range. (here "complete" means in the frequency range of the antenna)

regards

Hi
I think it's useful mostly for phased array antenna. there you have to measure
a lot of scanning beams but if you have constant beam just scan it in frequency domain
