LPI Sequences Optimization Method against Summation Detector Based on FFT Filter Bank

Remote Sensing
Waveform design is a crucial factor in electronic surveillance (ES) systems. In this paper, we introduce an algorithm that designs a low probability of intercept (LPI) radar waveform. Our approach directly minimizes the detection probability of summation

Detection and classification of low probability of intercept radar signals using parallel filter arrays and higher order statistics [PDF]

, 2002
The term Low Probability of Intercept (LPI) is that property of an emitter that because of its low power, wide bandwidth, frequency variability, or other design attributes, makes it difficult to be detected or identified by means of passive intercept ...

Classification and analysis of low probability of intercept radar signals using image processing [PDF]

, 2003
The characteristic of low probability of intercept (LPI) radar makes it difficult to intercept with conventional signal intelligence methods so new interception methods need to be devel-oped.

Automatic Modulation Classification of LFM and Polyphase-coded Radar Signals [PDF]

Radioengineering, 2017
There are several techniques for detecting and classifying low probability of intercept radar signals such as Wigner distribution, Choi-Williams distribution and time-frequency rate distribution, but these distributions require high SNR. To overcome this
