Radar Ppt All 5 Units Pdf Radar Transmitter In general, an increase in gain is accompanied by a decrease in beamwidth, and is achieved by increasing the antenna size relative to the wavelength. with regard to radar, high gain and narrow beams are desirable for long detection and tracking ranges and accurate direction measurement. Radar ppt free download as powerpoint presentation (.ppt .pptx), pdf file (.pdf), text file (.txt) or view presentation slides online. in this presentation , i tried to cover all details about radar technology i.e what is radar?. Coordinate systems • radar coordinate systems spherical polar: (r,θ,φ) azimuth elevation: (az,el) or (α ,γ ) • the radar is located at the origin of the coordinate system; the earth's surface lies in the x y plane.

Range resolution : is the ability of a radar system to distinguish between two or more targets on the same bearing but at different ranges. the degree of range resolution depends on the width of the transmitted pulse, the types and sizes of targets, and the efficiency of the receiver and indicator. pulse width is the primary factor in range. Sphere vs steradian the surface area of a sphere is 4πr2. the surface area of a steradian is just r2. so a sphere measures 4π steradians, or about 12.57 steradians. likewise a steradian is 1 12.57, or about 8% of a sphere. Introduction to radar radar = radio detection and ranging detects targets by receipt of reflected echoes from transmitted rf pulses measures metric coordinates of detected targets: range doppler velocity of targets angle (azimuth and or elevation). Basic radar principles prof. sandra cruz pol, ph.d. electrical and computer engineering uprm.
