Develop an automatic radar waveform detector using passive radio frequency
sensors such as existing radar receivers to detect, discern, classify, locate,
and track low-probability of intercept (LPI) radars.
The Navy is seeking algorithms and processing technology that can automatically
determine radar waveform parameters to detect, discern, and classify LPI
radars. Waveform parameters include for example: bandwidth, waveform
flexibility, phase shift coding, pulse code modulation as well as signal
strength and direction. Time-frequency analysis and machine learning techniques
have shown the potential to achieve automatic radar waveform recognition.
Recent open literature has begun to address LPI waveform recognition techniques
utilizing feature extraction and classification techniques to extract features
from the intercepted signal and to classify the intercepted signal based on the
extracted features. We seek to refine and extend such techniques.
I: Develop techniques and demonstrate the potential to derive automatic radar
waveform profiles with passive radar sensing using simulations. Determine
potential performance for different passive radio frequency receiver sensors.
Evaluate the potential performance to detect LPI radars and determine location
information to aid tracking. The Phase I effort will include prototype plans to
be developed under Phase II.
II: Demonstrate technical capability with real data using a radio frequency
detector. Quantify effectiveness and performance.
III DUAL USE APPLICATIONS: Complete development, integration, and transition to
Naval airborne surveillance platforms. The general approach may find use in law
enforcement applications where LPI communication techniques are used by those
