چکیده

A self-contained statistical analysis of the Pisarenko method for estimating sinusoidal frequencies from signal measurements corrupted by white noise is presented. An explicit formula is provided for the asymptotic covariance matrix of the joint estimation errors of the minimum eigenvalue and the minimum eigenfilter coefficients of the data covariance matrix. Our theoretical results extend and reinforce previous results obtained by Sakai [l]. A numerical study of the performance of the Pisarenko method, and a comparison with the performance achieved by the YuleWalker method are also reported.

Tracking systems for satellite communications - Radar and Signal Processing [see also IEE Proceedings-Radar, Sonar and Navigation], IEE Proceeding

Satellites in nominally geostationary orbits possess diurnal motion which causes the apparent position of the spacecraft to wander in the sky as seen by an earth station. If uncompensated this causes a variation in the performance of the communications link. The motion of the satellite therefore has to be tracked by the earth station antenna. During the past twenty years or so a considerable am...

Iterative Procedure for Real Single-tone Frequency Estimation

In many situations, a signal consisting of a single tone corrupted by additive white noise is available, and the frequency of the tone must be estimated. This problem has applications in communications, radar, sonar, measurements, adaptive control, speech processing etc [1], and it belongs to the wider class of spectrum estimation problems [2]. Both complex and real signals have been considered...

Performance Analysis of Etdge ; an Eecient a N D U N Biased Tdoa Estimator

A computationally eecient estimator is proposed which can provide instantaneous delay measurement for many practical applications such as radar, sonar and geolocation via satellites. It consists of an adaptive FIR lter to model the time diierence of arrival (TDOA) between the received signals from two sensors and a variable gain to adapt to the changing signal-to-noise ratio environment. The TD...

Analysis of micro-Doppler signatures - Radar, Sonar and Navigation, IEE Proceedings -

Mechanical vibration or rotation of a target or structures on the target may induce additional frequency modulations on the returned radar signal which generate sidebands about the target’s Doppler frequency, called the micro-Doppler effect. Micro-Doppler signatures enable some properties of the target to be determined. In the paper, the micro-Doppler effect in radar is introduced and the mathe...

A Modified Grey Wolf Optimizer by Individual Best Memory and Penalty Factor for Sonar and Radar Dataset Classification

Meta-heuristic Algorithms (MA) are widely accepted as excellent ways to solve a variety of optimization problems in recent decades. Grey Wolf Optimization (GWO) is a novel Meta-heuristic Algorithm (MA) that has been generated a great deal of research interest due to its advantages such as simple implementation and powerful exploitation. This study proposes a novel GWO-based MA and two extra fea...
