A Method of Relative Delay Measurement for the Wideband Digital Array Radar Based on Dechirping Technique
基于Dechirping技术的宽带全数字阵列雷达时延测量方法研究

In this paper, based on the Dechirping technique, a new method of measuring relative delays among digital T/R modules for the wideband digital array utilizing wideband LFM pulses is proposed. To enhance radar system's flexibility and extensibility and reduce hardware costs, this method can be realized by software. By using the decimation and FFT algorithm, not only can the measurement method be easier to be implemented for computational efficiency and reduce data rate, but also good measurement precision an...
