本发明介绍一种基于表面声波干涉原理的测向和测频方法及装置。该装置采用多个色散延迟线,目的在于由带有相位信息的脉冲串表示多副天线上具有不同频率及到达角的信号。分析脉冲串的脉冲间隔——这些间隔表示到达本发明天线的多个信号之间的频差,并对每个天线上同一信号之间的脉冲进行比较,可以实现信号的选择相关。
The present invention introduces a method and an apparatus for direction finding and frequency measurement based on the principle of surface acoustic wave interference. The device uses a plurality of dispersion delay lines, the purpose of which is to indicate, by a burst with phase information, signals with different frequencies and angles of arrival on multiple pairs of antennas. Analyzing Burst Pulse Interval - These intervals represent the frequency difference between multiple signals arriving at the antenna of the present invention and comparing the pulses between the same signal on each antenna to achieve a selective correlation of the signals.
