How to compute the location of the antenna when I rotate it?

Click For Summary

Discussion Overview

The discussion centers around the computation of the location of an antenna when it is rotated, specifically in relation to the amplitude and phase of the signal as described by complex exponential functions. Participants explore the implications of these equations in the context of antenna positioning and signal detection.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions how to define the amplitude and phase based on the unknown values of x and y when the antenna is rotated.
  • Another participant expresses confusion regarding the relevance of the equations and the equipment involved in the discussion.
  • A different participant suggests that the question may relate to a previous discussion on multipath detection, indicating a potential connection to earlier topics.

Areas of Agreement / Disagreement

Participants do not appear to agree on the clarity of the original question, with some expressing confusion and others suggesting it connects to prior discussions. The discussion remains unresolved regarding the specific computations and definitions needed.

Contextual Notes

There are limitations in understanding the relevance of the equations to the equipment being used, and the assumptions regarding the relationship between the antenna's rotation and the signal parameters are not fully articulated.

Hi group,

I have a question regarding to detect the location of the antenna.
I read this link: https://en.wikipedia.org/wiki/Plane_wave
In the "Complex exponential form" part, the equation:
U(r,t) = U0 * exp(j*(k.r - w*t) as the function of location and time
U0 = A0 * exp(j*phi) : A0 and phi are amplitude and phase respectively.
From U0, I can write down a complex number x and y (still in time domain)
x and y should be vector on the complex coordinate.

Now, I need to define value of amplitude and phase base on value of x and y. But I do not know x and y.
When I rotate the antenna, can I define the position, amplitude and phase?

I hope anyone can give me suggestions.

Thank you.

I do not understand the question, what you are trying to do, the relevance of the equations or the equipment you are using.
