A process for the auto regressive detection of a complex sinusfoermigen signal to noise and the estimation its frequency and apparatus for the carrying out the process, in particular for the detection of a target in a pulse radar signal

摘要

the invention relates to a process for the autoregressive coverage of a complex sinusoidal signal in noise and the estimation of its frequency and a device for the implementation ofin the proceedings, in particular for the collection of a target in a impulsradarsignal.$a to vorfiltern (ccr1, ccrp, fp1, ftp) for the determination of a useful signal in weiu00dfrauschen,a koeffizientsrechner (cr1) determines the reflexionskoeffizienten first order in the autoregressive analysis of the filtered signal; this reflexionskoeffizient is a erfassungsschaltung(cd) to the him with a rauschreferenz compares the calculatedto the information x (i) on the presence or the absence of a target in the auflu00f6sungszelle $i1 can be established.the reflexionskoeffizient is also sent to a argumentsrechenschaltung (cca)the argument of the complex coefficients are calculated from the frequency of the useful signal are derived. $a application: in particular, for the collection of radarziele.
