“…In [2,3], UWB through-wall motion sensing radars and UWB ground penetrating radars (GPRs) are introduced to meet the requirements of special war field and the probe and rescue after a natural disaster. Recently, Liang et al initiated the target detection in foliage using UWB radars and proposed that the log-logistic model was much suitable to represent UWB propagation channel in the foliage [4,5]. Then, the sense-through-foliage target detection using UWB sensors is investigated in [6][7][8].…”

Ultra-wideband impulse radio (UWB-IR) sensor network has intensive military and commercial applications. However, the interference between UWB and other existed networks should be casually investigated. In this paper, we consider interference mitigation in UWB sensors in the context of cognitive radio (CR). Firstly, we suggest a general state transition model to characterize the working states evolution of legal networks, also referred to as primary users (PU). Spectrum sensing, used to identify the state of PU, is formulated as detection of a corresponding state sequence. Maximum posterior probability (MAP) criterion is adopted to perform spectrum sensing. By exploring potential gain of state transitions, detection probability for nearby networks is improved significantly. Subsequently, based on the radius basis function neural network (RBF), we present a novel spectrum sculptor to design UWB waveforms. Attributed to the excellent reconfiguration of RBF, our scheme can produce UWB waveforms tracing available spectrums. The designed waveforms can entirely utilize multiple unoccupied bands to maintain uninterrupted communications. Also, sufficient spectral attenuation can be generated in specific bands to mitigate mutual interference between UWB sensors and other networks. Besides, orthogonal waveforms can be easily derived, which either improves transmission performance or provides a flexible accessing strategy for UWB sensors.

“…For example, reference [3] verified that using the log-logistic statistic model to describe the foliage clutter measured by the UWB radar is more accurate, rather than lognormal, Weibull and Nakagami. However, it is evident that the characteristics of vegetation clutter may vary a lot on the basis of different radar systems, signal forms, tree species and other forest characteristics.…”

We examined the reliability of a vegetation clutter model in the time-frequency domain using ultra high frequency (UHF) linear frequency modulation continuous wave (LFMCW) radar. The swaying vegetation is considered as a set of oscillators with a certain distribution density, according to the species of trees, yet with different amplitudes and different periods for various weather conditions. We were aiming to demonstrate that, by setting the parameters in our oscillating model appropriately, we could discover some properties of clutter data measured in a typical grove situated in southern China. The results of our work provide insight for the development of clutter modeling techniques that may be required for foliage penetration (FOPEN) radar.

“…This method has been used in previous researches to model the clutter signal for different types of clutter signal with different values of operating frequency [8][9][10][11]. This paper is the continuous work to model the clutter signal for the statistical analysis that has been done in Terengganu seaside measured using FSR with 434 MHz as presented in [12].…”

An empirical model for Terengganu seaside clutter measured using forward scatter radar (FSR) with operating frequency of 434 MHz is presented in this paper based on the analysed characteristics. Statistical distribution approach is used in this analysis to model the si clutter-like signal. To validate the accurateness between the measured and simulated clutter signal, the envelope clutter signal and the number of fit shape factor for both signals are being compared, while root mean square error (RMSE) technique i error between the measured and simulated clutter signal.
