- a high-resolution method for frequency measurement is strongly introduced in the paper, which is aim at detecting the frequency of regular and binary phase coding modulated pulse signals with high frequency precision . considering the popularity of linear frequency modulated ( lfm ) signal in electronic systems, this paper then referred a radon-stft arithmetic to calculate the carry frequency of lfm signal . both of these methods referred above are implemented in the signal if detection software
針對常規脈沖調制信號和脈內二相編碼調制信號,本文提出一種高精度的數字化測頻方法,以提高信號載頻測量精度;線性調頻信號作為一種典型的非平穩信號在各種領域應用十分廣泛,但對其載頻的數字化測量比較困難,本文利用圖像處理中的radon變換與信號時頻分析中的線性變換相結合的算法來完成對其載頻的測量。
