In a uniform linear array, increasing the number of similarly spaced elements while maintaining a comparable aperture arrangement generally tends to?

  • AIncrease directivity and narrow the main beam
  • BReduce directivity to zero
  • CMake all sidelobes disappear automatically
  • DMake element spacing irrelevant
Report an error
Correct Answer: A. Increase directivity and narrow the main beam
Explanation: More coherently combined elements generally provide a larger effective aperture, higher directivity and narrower main beam.
