OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. sparse Fourier representation of off-grid targets with application to experimental radar data. Abstract The problem considered is the estimation of a finite number of cisoids embedded in white noise, using a sparse(More)

Within the scope of sparse signal representation, we consider the problem of velocity ambiguity mitigation for wideband radar signal. We present a Bayesian robust algorithm based on a new sparsifying dictionary suited for range-migrating targets possibly straddling range-velocity bins. Numerical simulations on experimental data demonstrate the ability of(More)
In this paper, we consider the problem of estimating a signal of interest embedded in noise using a sparse signal representation (SSR) approach. This problem is relevant in many radar applications. In particular, estimating a radar scene consisting of targets with wide amplitude range can be challenging since the sidelobes of a strong target can disrupt the(More)
We consider the problem of estimating a finite number of atoms from a dictionary embedded in white noise, using a sparse signal representation (SSR) approach, a problem which is relevant in many radar applications. In particular, the estimation of a radar scene consisting of targets with wide amplitude range can be challenging since the sidelobes of a(More)

Extrinsic eye muscles respond to both proprioceptive and visual impulses. Histology of ocular proprioceptive receptors shows them to be qualitatively and original, neuromuscular bundles are found in primates, and so called "palisade sensory nerve endings" in felines. Golgi's osteotendinous receptors are apparently absent. The number of muscle receptors is(More)
Audio-impedence, vestibular, caloric, and electronystagmograph tests were conducted in 22 patients with benign paroxysmal vertigo. The disorder is provoked by certain sudden head movements, a latency period of several seconds occurring between the end of the movement and the onset of vertigo. This markedly differentiates it from other types of vertigo. It(More)
