Array object. 

Incoming signals, specified as an Mcolumn matrix. Each column
of 

Directions from which incoming signals arrive, in degrees. If If 

Carrier frequency of signal in hertz. Default: 

Propagation speed of signal in meters per second. Default: Speed of light 

Received signals. 
Simulate the received signal at a 6element URA. The array has a rectangular lattice with two elements in the row direction and three elements in the column direction.
The signals arrive from 10 degrees and 30 degrees azimuth. Both signals have an elevation angle of 0 degrees. Assume the propagation speed is the speed of light and the carrier frequency of the signal is 100 MHz.
hURA = phased.URA([2 3]); y = collectPlaneWave(hURA,randn(4,2),[10 30],1e8,... physconst('LightSpeed'));
collectPlaneWave
modulates the input signal
with a phase corresponding to the delay caused by the direction of
arrival. This method does not account for the response of individual
elements in the array.
