Abstract: A pulse description word (PDW) data preprocessing and detection method for modulation analysis in a pulse are disclosed. A lot of PDW data, which is generated by a channelized digital receiver with radar signals, is successively arranged according to the time of arrival (TOA). The PDW data which the TOA, a frequency, and a pulse width are overlapped is deleted. When the frequency is swept and the PDW data divided into a plurality of channels is generated, the PDW data is combined based on a set of sweep information and generation channel information. When the frequency is hopping and the PDW divided into the channels is generated, the PDW data is combined based on the information for the TOA and the pulse width. A PDW used for the modulation analysis in the pulse is selected based on a performance result. Optical PDW data capable of accurately recognizing the type of the modulation in the pulse corresponding to an importance identification variable is detected. The importance identification variable improves the radar signal identification ability of an electron source system.

Abstract: PURPOSE: A method and a device for extracting a radar signal jitter pulse repetition interval (PRI) pulse train using an adaptive histogram are provided to improve the detection accuracy of a radar signal in a high density multiple signal environment and to be applied to various electronic warfare systems necessary to be analyzed in signals. CONSTITUTION: A signal receiving part (10) comprises an antenna for sensing a radar signal. The signal receiving part processes the signal detected by the antenna and transmits the signal to a control part (20). The control part is classified into a histogram generation module (22), a candidate list setting module (24), a histogram extension module (25), an extraction threshold comparing module (26), and a jitter PRI pulse train extraction module (28). The histogram generation module generates a histogram using the difference between a set disparity and the time of arrival (TOA). The candidate list setting module selects a Bin which exceeds a pre-set candidate threshold among a histogram Bin and sets the Bin as a candidate list. The histogram extension module merges the histogram Bin in order to choose PRI for extraction using the candidate list. The extraction threshold comparing module compares the stored candidate list with the extracted threshold to determine whether to extract or not. The jitter PRI pulse train extraction module restarts the control operation by confirming the number of pulses remained after the extraction is greater than the jitter PRI pulse train accreditation number and increasing degree.
