Generation of Low Probability of Intercept Signals
Vulnerability in the interception of radar transmission by anti-radiation missiles or the like, can be avoided by using Low Probability of Intercept (LPI) techniques like Barker codes, Frank codes, polyphase codes, Costas code, etc. In this project, we simulate different kinds of complex waveforms that are obtained by superimposing LPI signal onto the radar signal. Analysis of the power spectra...
متن کاملIntercept Receiver Signal Processing Techniques to Detect Low Probability of Intercept Radar Signals
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 (RWR...
متن کاملDetectability models for multiple access low-probability-of-intercept networks
The concept of multiple access low-probability-ofintercept (LPI) networks has generated considerable interest in the past few years, due to increased demands for highly connected, yet covert, communications in the tactical battlefield. A number of research efforts have concentrated on network design issues, such as throughput, packet switching, and message routing, while others have focused on ...
متن کاملDetection and Parameter Extraction of Low Probability of Intercept Radar Signals using the Hough Transform
Digital intercept receivers are currently moving away from Fourier-based analysis and towards classical time-frequency analysis techniques, such as the Wigner-Ville distribution, ChoiWilliams distribution, spectrogram, and scalogram, for the purpose of analyzing low probability of intercept radar signals (e.g. triangular modulated frequency modulated continuous wave and frequency shift keying)....
متن کاملLow probability of intercept-based adaptive radar waveform optimization in signal-dependent clutter for joint radar and cellular communication systems
In this paper, we investigate the problem of low probability of intercept (LPI)-based adaptive radar waveform optimization in signal-dependent clutter for joint radar and cellular communication systems, where the radar system optimizes the transmitted waveform such that the interference caused to the cellular communication systems is strictly controlled. Assuming that the precise knowledge of t...
