Complementary Waveform Coordination for Doppler-Resilient MIMO Radar
Maksim Antonik, Wenbing Dang, Ali Pezeshki +2
Complementary waveform libraries yield impulse-like aggregate delay responses at zero Doppler, but pulse-dependent Doppler phases degrade their sidelobe cancellation. This paper de…
Group-Theoretic Wideband Radar Waveform Design
Kumar Vijay Mishra, Samuel Pinilla, Ali Pezeshki +1
We investigate the theory of affine groups in the context of designing radar waveforms that obey the desired wideband ambiguity function (WAF). The WAF is obtained by correlating t…
Coordinating Complementary Waveforms for Suppressing Range Sidelobes in a Doppler Band
Wenbing Dang, Ali Pezeshki, Stephen D. Howard +2
We present a general method for constructing radar transmit pulse trains and receive filters for which the radar point-spread function in delay and Doppler (radar cross-ambiguity f…
Subspace selection for projection maximization with matroid constraints
Zhenliang Zhang, Yuan Wang, Edwin K. P. Chong +2
Suppose that there is a ground set which consists of a large number of vectors in a Hilbert space. Consider the problem of selecting a subset of the ground set such that the projec…
Threshold Effects in Parameter Estimation from Compressed Data
Pooria Pakrooh, Louis L. Scharf, Ali Pezeshki
In this paper, we investigate threshold effects associated with swapping of signal and noise subspaces in estimating signal parameters from compressed noisy data. The term threshol…
Modal Analysis Using Sparse and Co-prime Arrays
Pooria Pakrooh, Louis L. Scharf, Ali Pezeshki
Let a measurement consist of a linear combination of damped complex exponential modes, plus noise. The problem is to estimate the parameters of these modes, as in line spectrum est…
