- The application of multiple digital phase - locked technology and the high frequency complementary symmetrical pulse technology is the key content discussed in the paper
多重數(shù)字鎖相技術在同步環(huán)節(jié)中的應用和本相高頻互補對稱脈沖技術在脈沖觸發(fā)中的應用，是本文探討的核心內(nèi)容。 - The pseudorandom codes have a good autocorrelation of double - values . in recent years , to solve the problems of anti - interference and the ambiguity of range and velocity , a lot of countries do much research to change the waveform of radar signal . the most important improve is to use symmetrical pulses to interrupt frequency modulated continuous wave ( fmpcw )
早期的fmicw采用偽碼序列截斷,偽隨機碼具有良好的雙值自相關特性,其中最常用的是m序列截斷的fmicw 。近年來,為了解決抗干擾和測距、測速模糊問題,許多國家已對雷達信號波形的改進進行了研究。 - Based on the analysis of the beat frequency signal , the expression of the beat frequency phase is deduced . the expression indicates physics meanings of quantities to be detected and supplies theoretical bases for detection methods . by using two - dimensional fft , the range and velocity information of target is got out from the echo . according to the periodicity range ambiguity of symmetrical pulses in fmpcw , the processing method of sliding time window is used
通過對差頻信號進行的分析,得出了差頻相位的具體表達式,表現(xiàn)出了要檢測的各量的物理意義,對檢測的方法提供了理論依據(jù)。利用二維fft方法,可以有效地提取回波中目標的距離與速度信息。對于fmpcw信號由于均勻脈沖產(chǎn)生的周期性距離模糊的問題,采取時間波門的處理方法。
