Color TV Transmission: Having discussed the manner of indicating luminance and the two components of chrominance in Color TV Transmission, it is now necessary to investigate how they may be,…
Color TV Transmission and Reception: If color TV had come before monochrome TV, the system would be far simpler than it actually is now. Since only the three additive primary…
Vertical Deflection Circuit in TV: The Vertical Deflection Circuit in TV include the vertical oscillator and amplifier for vertical scanning at 60 Hz and a similar horizontal arrangement for scanning…
CW Doppler Radar Block Diagram: A simple CW Doppler Radar Block Diagram, such as the one shown in Figure 16-14, sends out continuous sine waves rather than pulses. It uses…
Phased Array Radars: Phased Array Radars - Introduction With some notable exceptions, the vast majority of radars have to cover an area in searching and/or tracking, rather than always being…
Frequency Modulated Continuous Wave Radar: The greatest limitation of Doppler radar, i.e., its inability to measure range, may be overcome if the transmitted carrier is Frequency Modulated Continuous Wave Radar.…
Moving Target Indicator Radar Block Diagram: Basically, the Moving Target Indicator Radar Block Diagram compares a set of received echoes with those received during the previous sweep. Those echoes whose…
Doppler Effect in Radar: The apparent frequency of electromagnetic or sound waves depends on the relative radial motion of the source and the observer. If source and observer are moving…
