For a multiple-input multiple-output (MIMO) radar system adopting the Neyman-Pearson (NP) criterion, a detection algorithm for MIMO radar with arbitrarily correlated observation channels in the presence of possible Non-Gaussian clutter-plusnoise is analyzed. Simulation results show that both the correlation of the observation channels and the correlation of the clutter-plus-noise will reduce th...

In intelligent radar, it is an important problem for the transmitted waveform to adapt to the environment in which radar works. In this paper, we propose mutual information model of adaptive waveform design, which can convert the problem of adaptive waveform design into the problem of optimization. We consider two situations of no clutter and clutter and use Newton method and interior point met...

in this paper, the detection of moving targets in airborne widely separated phased multiple input multiple output (mimo) radars which are located on moving platform is investigated. in order to derive the detector, the generalized likelihood ratio test is applied. the proposed detection rule, exploits the clutter subspace information and its maximum likelihood estimation, to improve the detecti...

The estimation of rainfall rate and other parameters from radar scattering volume is heavily affected by the presence of intense sea and ground clutter and echoes which appears in anomalous propagation condition. To deal with these non meteorological echoes we present a new clutter removal algorithm which combines the results of previous works. The algorithm fully exploits both the Doppler and ...

Recent radar research interests in the Pareto distribution as a model for X-band maritime surveillance radar clutter returns have resulted in analysis of the asymptotic behaviour of this clutter model. In particular, it is of interest to understand when the Pareto distribution is well approximated by an Exponential distribution. The justification for this is that under the latter clutter model ...

In this study, to detect person-borne concealed threats in range profiles under the circumstance of unknown clutter, we propose a binary integration nonparametric detection method based on the generalized sign (GS) detector for range-spread targets in a distributed terahertz radar network (DTRN). In the detection, the length of range-spread targets and the number of dominant scatterers on range...

Abstract The performance of Space-Based Radar (SBR) to detect air or ground moving targets is influenced by earth clutter, so an effective algorithm to suppressing clutter can be designed if knowing the power and distribution of earth clutter. In this paper, the clutter model of SBR is deduced. Besides, the earth's rotation effect is taken into account and the modification to Doppler frequency ...

Target tracking algorithms in radar systems have to operate in an environment of measurement uncertainty. A condition for good target tracking in a radar system is that a target position can be estimated and the measurement accuracy can be determined. The main problem is that clutter cannot be well defined by a stationary stochastic process and there is no known general model that works in diff...

Wind Turbine Clutter (WTC) mitigation is a challenging issue that worldwide weather services are facing at the moment. The use of wind farms to generate electricity is growing increasingly due to the importance of being a renewable energy source. Wind farm installations relatively near to weather radars may block the normal propagation of the radar signals and cause reflectivity clutter returns...

Generalized Order Statistic Cell Averaging (GOSCA), Generalized Order Statistic Greatest Of (GOSGO), and Generalized Order Statistic Smallest Of (GOSSO) CFAR detectors are proposed. Each of them has its own advantages according to radar environment situations so that most effective radar detector can be chosen at any unpredictive situation. Their performance formulas in terms of false alarm pro...
