Some extensions of the K distribution

2013
In this chapter we have seen how the relatively simple theoretical ideas underlying the K distribution model of sea clutter that were discussed in Chapters 6 and 7 can be extended, both in terms of their physical content and of the mathematical techniques used in their analysis.

CFAR detection in K-distributed clutter

ICSP '98. 1998 Fourth International Conference on Signal Processing (Cat. No.98TH8344), 2002
CFAR detection in K-distributed clutter is addressed. First, we discuss the compound K-distribution model, correlated K-distribution model and the simulation of K-distributed clutter, and then summarize the methods of CFAR detection in K-distributed clutter.

Correlated K-distributed Clutter Models

Optica Acta: International Journal of Optics, 1985
In this paper we examine the way in which a correlated K-distributed clutter model may be applied in the study of coherent-imaging systems. The theoretical background behind the model is discussed and various different correlated gamma-distributed surface models are analysed.

Estimating the correlation properties of k-distributed SAR clutter

IEE Proceedings - Radar, Sonar and Navigation, 1995
The authors extend previous analysis of the texture properties of k-distributed SAR clutter by including spatial correlation properties. Throughout they compare operating in the intensity domain with using its logarithm or square root (amplitude).

Roth 401(k) Distribution Confusion

Compensation & Benefits Review, 2007
Now that Roth 401(k) contributions are permanent, many employers may revise their plans, resulting in an increase in Roth contributions and distributions.

Broadband detection in K-distributed reverberation

Sensor Array and Multichannel Signal Processing Workshop Proceedings, 2002, 2003
In active sonar, broadband waveforms can improve the signal-to-reverberation power ratio (SRR) by decreasing the size of the resolution cell. Unfortunately, this can adversely affect detection performance by spreading the target across several cells and adversely affect false alarm performance by making the reverberation more severely non-Rayleigh. The

K-distributed coherent sea clutter

IEE Proceedings F Radar and Signal Processing, 1991
The properties of coherently detected high-range-resolution radar sea clutter are examined with reference to those properties observed noncoherently. It is shown here how the nonGaussian characteristics of noncoherently detected sea clutter manifest themselves in the coherent domain and how these characteristics require a thorough understanding in ...

Special functions associated with the K distribution

2013
In this chapter, we discuss the special functions associated with the K distribution. These functions are gamma function, K distribution PDF, Bessel function, Laguerre polynomial and Hermite polynomial.

Modeling of K Distribution Radar Clutter

2011
In order to solve the modeling problems of radar simulation. Started with the character of clutter, proposed the feasible plan to produces the clutter with specific frequency spectrum, its modeling and simulation was achieved through zero memory nonlinearity, the detailed steps for modeling the radar clutter with K Distribution is presented.
