Intercept Receiver Signal Processing Techniques to Detect Low Probability of Intercept Radar Signals
نویسنده
چکیده
Many users of radar today are specifying a Low Probability of Intercept (LPI) as an important tactical requirement. The term LPI is that property of a radar that because of its low power, wide bandwidth, frequency variability, or other design attributes, makes it difficult to be detected by means of passive intercept receiver devices such as electronic support (ES), radar warning receivers (RWRs), or electronics intelligence (ELINT) receivers. It follows that the LPI radar attempts to provide detection of targets at longer ranges than intercept receivers can accomplish detection of the radar. The success of a LPI radar is measured by how hard it is for the receiver to detect the radar emission parameters.

Low Probability of Intercept Frequency Hopping Signal Characterization Comparison using the Spectrogram and the
Low probability of intercept radar signals, which are often problematic to detect and characterize, have as their goal ‘to see and not be seen’. Digital intercept receivers are currently moving away from Fourier-based analysis and towards classical time-frequency analysis techniques for the purpose of analyzing these low probability of intercept radar signals. This paper presents the novel appr...

متن کاملA Novel Method for Recognition of Modulation Code of LPI Radar Signals
The Low Probability of Intercept (LPI) capability of the radar defeats conventional RWR/ESM systems. The important advantage of LPI radar is to go undetected, while maintaining a strong battlefield awareness. Common Spectral analysis and conventional methods fail to detect emissions of LPI Radars and even normal radars in noisy environments. This leads to use Higher Order Spectral Analysis (HOS...
