11. Beam width is determined by length of the sonar array, narrower beams resolve finer detail.12. The beam width can either be fixed or variable. 13. One approach that uses a variable beam width starts with the width at a minimum. 14. It was hoped by doing this that the beam width problems with Fug25a would be resolved. 15. Some rely on the optics of the LED ( s ) to control the beam width . 16. This vulnerability begins in the low-elevation region several beam widths above the horizon, and extends downward. 17. The beam width at exit of the driver system is about 40 cm ?40 cm. 18. A "'high-gain antenna "'( HGA ) is a directional antenna with a focused, narrow radiowave beam width . 19. As with the VL5, there was also a set of diffuser vanes to alter the beam width . 20. X-ray section beam width was 15 micrometers.
