Abstract

THIS STUDY DEALS WITH ESTIMATING THE PARAMETERS OF THE RECEIVED SIGNAL OF THE POLY PHASE IN THREE ORDERS. THE PROCESS OF ESTIMATION OCCURS IN TWO STAGES: IN THE FIRST STAGE, THE HIGH ORDERS OF THE SIGNAL WERE ESTIMATED HIGHLY ACCURATELY USING THE NON UNIFORM FFT. THE RECEIVED SIGNAL PASSES THROUGH THE COMPONENTIAL MATCH FILTER WHICH HAS BEEN ESTIMATED HIGHLY ACCURATELY. AS IT PASSES THROUGH THIS FILTER, THE ORDER OF THE PLOY PHASE DECREASES. IN THE SECOND STAGE, THE COMPONENTS OF THE LOW ORDER OF THE PLOY PHASE SIGNAL ARE ESTIMATED HIGHLY ACCURATELY USING THE SHORT TIME FREQUENCY TRANSFORM (STFT) METHOD. FINALLY, THE FINDINGS OF THE STIMULATION IN THESE TWO STAGES INDICATED THE EFFICIENCY OF THE PRESENTED ALGORITHM FOR THE RECEIVED SIGNAL PARAMETERS INCLUDING THE INITIAL FREQUENCY, THE CHIRP RATE, AND THE CHANGE CHIRP RATE.
