Simulation and Analysis of Anti-jamming Algorithm Based on LFM Diff-pat Dealing
Yue Yu · Modern Radar · 2013
The signal model and operation principle of Transmitted range false target jamming and Smart noise jamming is discussed,put forward an algorithm of diff-pat dealing to suppress jamming,this algorithm take the previous pulse repeat interval as reference signal(not be jammed),carry out a fiff-pat dealing with the current pulse repeat interval(be jammed).Via diff-pat dealing,the target echo can be moved to the low frequency band,and the jamming signal will be moved to a higher frequency band in frequency domain,thus,a low pass filter can be utilized to cancel the jamming signal and then the target echo can be rebuilt through Inverse diff-pat dealing.
