Isotropic Antenna : Isotropic Antenna An antenna which transmitts radations equally in all directions. (1) S = Power flux density (watts/m2) Pt = Transmitted power Directional Antenna and Gain : Directional Antenna and Gain Isotropic antenna is not practical,so we use directional antenna. We have to consider the power flux density of direction antenna say Sd. Gain is the ratio of: Power flux density at radius r, for a directional antenna, to the power flux density for an isotropic antenna. (2) Slide 5: Using equation(1): (3) Power density at target. Power density decreases as a function of distance traveled. Reflected Power.. : Reflected Power.. (4) Radar cross section: “Ratio of the power flux density scattered by the target in the direction of the antenna to the power flux density. (5) Aircraft high RCS areas : Aircraft high RCS areas But.. : But.. We measure power density reflected at the radar and not on the target. so: (6) (7) Power of Echo at Receiver.. : Power of Echo at Receiver.. Antenna captures only a portion of the echoed power density. (8) So the power captured at receiver is: (9) Effective Aperture : Effective Aperture From antenna theory: (10) Substituting (10) in (9): (11) Maximum Range: : Maximum Range: r=Rmax : This is the radar range equation You do not have the permission to view this presentation.
