Moreover, a space with an

azimuth angle of +/-60 and an elevation angle of more than 10 was to be covered.

Moreover, a space with an

azimuth angle of +/-60[degrees] and an elevation angle of more than 10[degrees] was to be covered.

This method gives an idea about

azimuth angle of the sound source.

M] is sometimes referred as hour angle and can be used to calculate

azimuth angle [[alpha].

i)(k) [theta](k): The pitching angle [phi](k): The

azimuth angle w(k): The measurement noise v(k): The process noise.

Refer to Fig 4, from which it can be easily observed that the slope of the graph at lower and upper angles of

azimuth angle, m =180 decreases, which means the PPD is not constant for all angles of azimuth and elevation for larger values of distance d.

Above the housing is a resolver which is used to measure antenna

azimuth angle.

where [theta] [member of] [0,[pi] ] is the signal's elevation angle measured from the positive z-axis; [phi] [member of] [0,2[pi] ] denotes the

azimuth angle measured form the positive a>axis; [gamma] [member of] [0, [pi] /2] represents the auxiliary polarization angle; [eta] [member of] [-[pi], [pi] ] symbolizes the polarization phase difference.

For the estimation of

azimuth angle, p = 1, the cost function is N-dimensional.

Input

azimuth angle of arrival for desired signal= -300 Input elevation angle of arrival for desired signal =400

If the motion error at the central position of the ith azimuth sub-aperture is [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] and the

azimuth angle is [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], which corresponds to a certain azimuth frequency [f.

2] is the mean-square sensitivity to sound waves that arrive at the device from an elevation angle [alpha] and an

azimuth angle [theta].
