A radar uses PRF = 5 KHz. Find the first three positive Doppler blind center frequencies. If the radar is 10 GHz, give the corresponding blind velocities in m/s.
A cellular system is operated at a carrier frequency of 1.9 GHz. For a mobile user traveling at a speed of 100 km/hr (a) Determine the maximum Doppler frequency,fo (b) In what situation, the Doppler frequency would equal to 0 Hz? (c) In what situation, the Doppler frequency would equal to fo2? (d) Assuming that the received power is P, - 0 dBm, draw the baseband power spectrum given below else
2. A search radar operates at 5 GHz by sending 3 MW pulses of 20 uus pulse duration. The gain of the radar antenna is 28 dB and the equivalent system noise temperature is 1400°K. The system loss is 1 dB. The radar cross section of a typical airplane viewed from the front is 30 mp. If the minimum signal-to-noise ratio (SNR) needed for detection is 20 dB, what is the maximum detectable range of the search radar?
