Estimation of ambiguity functions with limited spread
This paper proposes a new estimation procedure for the ambiguity function of a non-stationary time series. The stochastic properties of the empirical ambiguity function calculated...

Adaptive design of OFDM radar signal with improved wideband ambiguity function
We propose an adaptive technique to design the spectrum of an orthogonal frequency division multiplexing (OFDM) waveform to improve the radar's wideband ambiguity function (WA...

Doppler Resilient Golay Complementary Waveforms
We describe a method of constructing a sequence (pulse train) of phase-coded waveforms, for which the ambiguity function is free of range sidelobes along modest Doppler shifts. The...

New Sequences Design from Weil Representation with Low Two-Dimensional Correlation in Both Time and Phase Shifts
For a given prime p, a new construction of families of the complex valued sequences of period p with efficient implementation is given by applying both multiplicative characters a...
