incident angle for phased.WidebandCollector

This is my current code.

collector = phased.WidebandCollector('Sensor',array,...

'PropagationSpeed',c,'SampleRate',fs,...

'ModulatedInput',false);

incidentAngle = [50;30];

a = collector(x.',incidentAngle);

I dont understand the starting point of the azimuth angle as my array is have 11 elements. Does it starts count the angle in the middle or does it count from the right side or left side? or could I narrow the area down into a specific angle? Can someone please specify this for me. Thank you so much.

Hi,

‘phased.WidebandCollector’ has a ‘Wavefront’ property which can take two values(‘Plane’ or ‘Unspecified’)

1. When ‘Wavefront’ property is set to ‘Plane’. All the sensors have same Azimuth Angle and Elevation Angle.
2. When ‘Wavefront’ property is set to ‘Unspecified’. All the sensors Azimuth Angle and Elevation Angle has to specified by the user.

For more details check the below mentioned documentation.
