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:
- Linear Array with antenna positions known at hand
- 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)
- For synthesized pattern, we only care about mainlobe width and sidelobe level.
Any references are welcome
