In this paper, the algorithms for adaptive rejection of a radar clutter are synthesized for the case of a priori unknown spectral-correlation characteristics at wobbulation of a repetition period of the radar signal. The synthesis of algorithms for the non-recursive adaptive rejection filter (ARF) of a given order is reduced to determination of the vector of weighting coefficients, which realiz...

The problem of designing Spread Spectrum radar detection filters that minimize sidelobe levels in both Doppler and range co-ordinates is considered and a new algorithm for the Doppler optimized mismatched filter is presented. The Iterative Reweighted Least Square procedure for minimax filter coefficients calculation is applied. A special attention has been paid to the analysis of Code Division ...

dispersion and separated of agricultural lands are considered as the serious barriers of agriculture development. the smallest and distributed oflands are obstacle in the efficient use of water, land, labor, mechanization and other factors in agriculture production. the main purpose of this article is analyse the influenced factors of the rejection of land integration. the statistical populatio...

For a learning problem whose associated excess loss class is (β,B)-Bernstein, we show that it is theoretically possible to track the same classification performance of the best (unknown) hypothesis in our class, provided that we are free to abstain from prediction in some region of our choice. The (probabilistic) volume of this rejected region of the domain is shown to be diminishing at rateO(B...

Summary In this article, we propose a positive stable shared frailty Cox model for clustered failure time data where the frailty distribution varies with cluster-level covariates. The proposed model accounts for covariate-dependent intracluster correlation and permits both conditional and marginal inferences. We obtain marginal inference directly from a marginal model, then use a stratified Cox...

Purpose: The analysis of organizational diagnosis on based six box model at universities. Research method: Research method was descriptive-survey. Statistical population consisted of 1544 faculty members of universities which through random strafed sampling method 218 persons were chosen as the sample. Research Instrument were organizational diagnosis questionnaires with 77 items that by use of...

Considered is the problem of optimal rejection of persistent exogenous disturbances in dynamic systems. A robust formulation is given for the case where the matrix coefficients are subjected to norm-bounded uncertainties; the solution technique based on the invariant ellipsoids concept is developed. The approach is exemplified through a well-known benchmark control problem for a mechanical two-...

Dual band bandpass filter is designed and optimized for RF wireless applications. The performances of that RF dual band filter are improved especially parameters describing the insertion loss, return losses and rejection. Dual band bandpass filter using stub loaded resonators is designed and characterized. Theoretical results are compared with experimental data. This comparison shows that the m...
