Radar System Design Chapter 14. MTI and Pulsed Doppler Radar Radar System Design MTI and Pulsed Doppler Radar Moving Target Indication (MTI) Radar : A delay line canceller filter to isolate moving targets from nonmoving background - Ambiguous velocity - Unambiguous range Pulsed Doppler Radar : Doppler data are extracted by the use of range gates and Doppler filters. - Unambiguous velocity - Unambiguous or ambiguous range Chapter 14: MTI and Pulsed Doppler Radar 14 - 1 Dr. Sheng-Chou Lin Radar System Design Pulsed Radar High-PRF: unambiguous Doppler frequency , highly - Improve noise-limited detection relative ambiguous range to low-PRF waveform - solve TX-RX coupling problem of CW system - Minimize the number of introduced blind - Range blind during TX time periods zones relative to low-PRF system.
