broadside2az

Convert broadside angle to azimuth angle

Syntax

az = broadside2az(BSang,el)

Description

az = broadside2az(BSang,el) returns the azimuth angle, az, corresponding to the broadside angle BSang and the elevation angle, el. All angles are in degrees and in the local coordinate system. BSang and el can be either scalars or vectors. If both of them are vectors, their dimensions must match.

Examples

collapse all

Return the azimuth angle corresponding to a broadside angle of 45° and an elevation angle of 20°.

az = broadside2az(45,20)
az =

   48.8063

Return azimuth angles for 10 pairs of broadside angle and elevation angle.

BSang = (45:5:90)';
el = (45:-5:0)';
az = broadside2az(BSang,el);

Azimuth Angle

The azimuth angle az corresponding to a broadside angle β and elevation angle el is:

az=sin1(sin(β)sec(el))

where –90 ≤ el ≤ 90, –90 ≤ β ≤ 90, and –180 ≤ az ≤ 180 .

Together the broadside and elevation angles must satisfy the following inequality:

|β|+|el|90
