Which of the following equation gives the incremental phase shift of t

1.	Which of the following equation gives the incremental phase shift of the phase array radar with d element spacing and scan angle θ?(a) \(ᴪ=\frac{2π}{λ} dsinθ\)(b) \(ᴪ=\frac{2π}{d} λsinθ\)(c) \(ᴪ=\frac{π}{λ} dsinθ\)(d) \(ᴪ=\frac{π}{d} λsinθ\)The question was asked in a national level competition.I need to ask this question from Phased Array topic in portion Phased, Adaptive and Binomial Arrays of Antennas
Answer» The CORRECT choice is (a) \(ᴪ=\frac{2π}{λ} dsinθ\) Easiest EXPLANATION: The incremental phase SHIFT of the phase array radar with d element spacing and scan angle θ is given by \(ᴪ=\frac{2π}{λ} dsinθ\). The phase shifters are electronically tuned to ADJUST from 0 to 2π.
