چکیده
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 mathematics of micro-Doppler signatures is developed. Computer simulations are conducted and micro-Doppler features in the joint time–frequency domain are exploited.

Study of the statistical performance of the Pisarenko harmonic decomposition method - Radar and Signal Processing [see also IEE Proceedings-Radar, Sonar and Navigation], IEE Proceeding
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 ...

Proper design of receiver flight paths allows three-dimensional information to be encoded in sensed bistatic SAR phase history data. The authors show how the flight path taken by the receiving platform determines the resolution of nonparametric scene reconstructions and determines the variance of three-dimensional scattering centre location parameter estimates. Based on these relationships, a b...
متن کاملAdaptive algorithm for direct frequency estimation - Radar, Sonar and Navigation, IEE Proceedings -
Based on the linear prediction property of sinusoidal signals, a new adaptive method is proposed for frequency estimation of a real tone in white noise. Using the least mean square approach, the estimator is computationally efficient and it provides unbiased and direct frequency measurements on a sample-by-sample basis. Convergence behaviour of the estimated frequency is analysed and its varian...
متن کاملDevelopments in target micro-Doppler signatures analysis: radar imaging, ultrasound and through-the-wall radar
Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature. Radar micro-Doppler signatures are generally both target and action specific and hence can be used to classify and recognise targets as well as to identify possible threats. In recent years, research into...
