MATLAB: Bandwidth in Wideband Collector

bandwidthPhased Array System Toolboxwideband collector

I am trying to use Phased Array Toolbox to simulate a wideband antenna array. I know the bandwidth I want the array to receive signals across, but I don't see anywhere in the documentation that allows me to specify the bandwidth. How does a "wideband" collector in Phased Array Toolbox define what bandwidth is "wideband"?

Best Answer

The bandwidth in this case is derived from sample rate. When you specify a carrier frequency, fc, and a sample rate, fs, the bandwidth is considered as [fc-fs/2 fc+fs/2]. This bandwidth is then divided into subbands (number of subbands depends on the data length but is at least 128) to do the processing. Does this addresses your concern? Please let me know if you need further clarifications.
