Also, all these researches are centring on how to improve the blind separating effect in the complex electromagnetic environment: Huang first applied the technology of blind signal extraction to radar signal sorting and found feasible Li analysed the FastICA algorithm, used it in radar signal sorting, and achieved good separating performance Xiong raised a new improved algorithm combining the Newton method with negentorpy as an objective function to optimise the FastICA algorithm and eliminate the influence of the initial value. In the complex electromagnetic environment, radar signal blind separation is an effective method for radar emitter intropulse signal sorting. Radar signal sorting based on the intropulse parameters mainly selects distinctive features to represent each signal, such as multi-dimensional statistical features, time–frequency features, and entropy, by which the signal component is extracted in sequence. Also, signal sorting is finished according to the correlation of the same radar's parameters. At present, most of researches on the radar signal sorting are based on the interpulse parameters: carrier frequency, pulse width (PW), pulse repetition frequency, time of arrival (TOA), angle of arrival, pulse amplitude, etc. Radar signal sorting mainly depends on signal parameters, including interpulse and intropulse parameters.

Radar signal sorting aims to separate a single radar signal from the random mixed signal flows by the radar reconnaissance equipment in the high-density signal environment. Hence, it is vital to complete the radar signal sorting precisely and rapidly in the complicated environment. Radar signal sorting is the front part of radar emitter recognition, location, and tracking, whose result directly influences the latter reconnaissance counter-measure system's performance.

#Wavelet denoise archive#
If you really need something from the old site, there’s a static archive of the contents available on Github that you can access. Hopefully we’ll also have similar functionality to Firefox Add-ons to allow ratings, uploads, and more (both in a web-based interface and from within GIMP). This means that in the future there will be an interface within GIMP to browse and manage the same types of assets you used to find on the registry (plugins, scripts, brushes, etc.). The one and only Jehan is currently working on integrating the functionality of the old registry site with a new approach by bringing it into GIMP properly. On the good side, this cloud is not without a silver lining! This was not a trivial task to take over and the project is already stretched a little thin for volunteers.Ĭouple this with the fact that the interface and method of reaching users this way was outdated/needlessly complicated for users, and you can understand why we were ok with retiring the site. The problem is that the entire site was hosted on a very old installation of Drupal and there was nobody who was willing to step up and take ownership (including upgrading and maintaining the site long term).
