Pul: What is delay line canceller? Illustrate the concept of blind speeds based on frequency response of a simple debary line canceller ? Qn2: What is blind speeds ? Suggest a method to reduce the effect off blind speed for unambiguous detection of a moving target. On3: An MTI radar is operated at 95H2 with a PRF of 3080 pps. Catonlets the first Two lowest blind speed for this radar. Qn4: A low power, short range radar is solid-state throughout induding a low RF amplifier which gives it an overall noise figure of 4.77 dB. If the antenna diameter is I'm, If IF bandwidth is 500 KHE, the operating frequency is SHE and the radar set is supposed to be capable of detecting targets of 5m? cross sectional area at a maximum distance of 12 km what must be the peak transmitted power ! Q15. An 89H12 police Radar measures a Doppler frequency of 1788 H2 from a car approaching the stationary police vehicle in 80 kmlhr speed limit zone, what should the police officer do ? And: Calculate the lowest blind speed of an MTI Radar system operating at 3.6 cm wavelength and transmitting a pulse repetition timie of 330us . Ont: define the mouse figure for Radar receiver, and obtain an expression for the noise figure for 3 networks in cascade. @8: Three network units, each of EdB noise figure and 10 dB, GAB and 3 dB gains respectively are cascaded. Determine the overall nouse figure of the system . Ong : (@ How is NTI Radar differ from Pulse Doppler Radar? (B) How is MTI Radar differ from CW Raday
