Paper Title :
Delay-Doppler Performance Of Hyperbolic Frequency Modulation Waveforms

Author :A.Nagajyothi, K. Raja Rajeswari

Article Citation :A.Nagajyothi ,K. Raja Rajeswari , (2013 ) " Delay-Doppler Performance Of Hyperbolic Frequency Modulation Waveforms " , International Journal of Electrical, Electronics and Data Communication (IJEEDC) , pp. 62-65, Volume-1,Issue-9

Abstract : Doppler effect plays a vital role and cannot be neglected for high velocity radars. When the velocity between the target and radar is very high compared to the velocity of transmitted waveform, then the received signal suffers Doppler distortion and will not match with the matched filter. Due to this, linear frequency modulation waveform suffers from a considerable signal loss. Use of hyperbolic frequency modulation eliminates this adverse effect. In this paper hyperbolic frequency modulation waveform is shown as Doppler-invariant when compared with linear frequency modulation. The desired Doppler-invariant property of the hyperbolic frequency modulation is very attractive for radars employing pulse compression techniques. Schematic ambiguity diagrams are presented for linear frequency modulation and hyperbolic frequency modulation waveforms
