WebOct 13, 2016 · Orthogonal Frequency Division Multiplexing (OFDM) is an efficient modulation method which is widely used in many mobile communication systems. Applying OFDM signals to radar systems will make the combination of radar and communication systems in one single system platform possible. In this paper, the auto-correlation and … In pulsed radar and sonar signal processing, an ambiguity function is a two-dimensional function of propagation delay and Doppler frequency , . It represents the distortion of a returned pulse due to the receiver matched filter (commonly, but not exclusively, used in pulse compression radar) of the return from a moving target. The ambiguity function is defined by the properties of the pulse and of the filter, and not any particular target scenario.

WebApr 14, 2024 · $\begingroup$ Right you translate frequency only in one direction with a complex conjugate multiplier (which would model a Doppler shift as well). Any shift is periodic over period f_s, so a tiny shift negative is the same as a large shift positive. But you can always distinguish a small shift negative from a small shift positive. WebJul 9, 2024 · Abstract: Fast chirp FMCW MIMO radar with inter-chirp coding provides high emission power by utilizing simultaneous antennas transmissions.
