Intercept 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 کاملIdentification of LPI Radar Signal Modulation using Bi-coherence Analysis and Artificial Neural Networks Techniques
This paper presents Higher Order Spectral Analysis (HOSA) and Artificial Neural Network techniques for identification of LPI (Low Probability of Intercept) Radar signal. Common Spectral analysis and conventional methods fail to detect low powered emissions of LPI Radars and even normal radars in noisy environments. This leads us to use Higher Order Spectral Analysis (HOSA) techniques (bi-spectr...
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...
متن کاملGeneration 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 کاملDetection, Identification & Classification of Intra Pulse Modulated LPI Radar Signal using Digital Receiver
The modern day Electronic Warfare(EW) receivers are required to match with the current day radar technologies like the Low Probability of Intercept(LPI) radars with various intra pulse modulations such as Chirp, Barker, Frank, Poly-phase and Poly time codes. This paper presents the state of the art single board Digital Receiver solution for intercepting and analyzing complex radar signals. Also...
