Non-linear frequency estimation by non-linear estimator

The technique of estimating the complex frequency components a signal in presence noise based on assumptions about number is known as estimation. problem estimation appears when we receive from transmitter with frequency, and it often radar, sonar, etc. applications. This has been dealt by various techniques algorithms. research shows methods used researchers to estimate paper discusses between fixed sender receiver without movement through simulation Matlab using two algorithms: first correlation method, second Recursive least squares algorithm(RLS). best results were obtained changing controller gain filter coefficent internal source external source. Also, transfer function was changed several values get response its better parameter function.the also discussed case moving receiver,which found radar systems targets at or variable speed. Deep learning detect target bellows convolutional neural network(CNN), which proved be more accurate than others.
