This paper considers the unit energy phase-modulated (PM) waveform design in communications and radar. For a given scenario, the weighted integrated sidelobe level (WISL) of a waveform is often used as a metric to evaluate the performance of a system. The waveform design with the minimization of the WISL as the criteria is a high dimension search problem and the classical solution for the multi-dimension...
In this paper, we focus on the performance improvement of constant false alarm rate (CFAR) detector in heterogeneous Compound-Gaussian background. This paper is motivated by the fact that the detectors' performance degradation when an unknown located clutter edge exists in the reference window that divide the data samples into two different independent and identically distributed (IID) Compound-Gaussian...
Particle filter (PF) based multi-target tracking (MTT) methods suffer from the curse of dimensionality. Existing strategies to combat this assume posterior independence between target states, in order to then sample targets independently, or to perform joint sampling of closely spaced targets only. When many targets are in proximity, these strategies either perform poorly or are too computationally...
A new algorithm of range ambiguity resolution is presented which is substantially different from previously proposed algorithms. The algorithm utilizes a constant pulse repetition frequency (PRF). Firstly, a merit function is designed according to the moving characteristics of the targets. Secondly, range ambiguity resolution is achieved by minimizing the merit function. Numerical simulation results...
This paper addresses the detection strategy of a single pulse for range-distributed targets. The background is assumed to be compound Gaussian-distributed clutter with partially correlated clutter. Firstly, the definition of information entropy is introduced. Then, a new nonparametric detection strategy based on Renyi's quadratic entropy is proposed. Moreover, we present numerical results for the...
In this paper, we first introduce the definition of spherically invariant random vector (SIRV) and then give the representation of Weibull distribution by SIRV and two detection algorithms for Weibull clutter. In particular, the optimum detector is derived for the distributed target by the Neyman-Pearson (NP) criterion. Since the optimum NP detector is impossible to realize at the practical situations,...
