Plot the fixed beams of an N = 4 element array with d = 1/2. Fixed sidelobe canceller: The goal of the design is to choose array weights so that a null is placed in the direction of interference while the mainlobe maximum is in the direction of interest. Consider an N = 3 element array with d = 1/2. Calculate the array weights to receive the desired signal at = 30°, and to suppress the interfering signals arriving at 6₁ = -30° and 02=-60°.
