Autonomous Detection and Classification of Low Probability of Intercept Emitters
Course Length: 24 hours total - delivered across 8 sessions of 3-hours each
This course will cover the unified presentation of the fundamental design principles of LPI radar. This includes a thorough treatment of the numerous types of wideband modulations that can be used to reduce the probability of a noncooperative intercept receiver’s ability to intercept and extract the waveform modulation parameters (which may easily lead to an effective jammer response). We will also cover the intercept receiver time-frequency and bi-frequency signal processing techniques that can extract the wideband waveform parameters. Autonomous classification and parameter extraction algorithms are also an objective such that a real-time jammer response can be developed – just what we did not want to happen!
