There are tons of papers discussed this topics and most of them are related to fancy optimization techniques (convex/non-convex). I am wondering if we can have a simpler way to find the antenna weights if I restrict my requirement as following:

  1. Linear Array with antenna positions known at hand
  2. All antennas are located on a grid. For example, four antennas are located at (0, d, 4d, 6d) where d is a fixed distance (say, half wavelength)
  3. For synthesized pattern, we only care about mainlobe width and sidelobe level.

Any references are welcome

Thanks

  • $\begingroup$ If antenna positions are already known, what is it that you want to design/optimize? What are your degrees of freedom, what can you vary? $\endgroup$ – Florian Aug 26 at 11:59
  • $\begingroup$ a lot of signal processing is related to fancy optimization. since your array is sparse, you could search on sparse FIR filter design. $\endgroup$ – Stanley Pawlukiewicz Aug 26 at 12:45
  • $\begingroup$ @Florian The antenna positions are known and I would like to to know the weights. I know it is better to do a joint design. But searching for a good antenna positions are usually not very easy. $\endgroup$ – Yan Zhu Aug 29 at 5:21
  • $\begingroup$ @YanZhu still not sure what you mean by weights. Are you trying to do beamforming? Because you never mentioned that. $\endgroup$ – Florian Sep 5 at 16:01
