Question: Which expression suits best when the solid angle obtained by the noise source is less than antenna solid angle?
Options
A : PA ?A=PB ?B and ?TA=\frac{\Omega_B}{\Omega_A} T_B
B : PA ?B=PB ?A and ?TA=\frac{\Omega_B}{\Omega_A} T_B
C : ?TA=\frac{\Omega_A}{\Omega_B} T_B and PA ?B=PB ?A
D : ?TA=\frac{\Omega_A}{\Omega_B} T_B and PA ?A=PB ?B
