Direction detector for distributed targets in unknown noise and interference [PDF]
Adaptive detection of distributed radar targets in homogeneous Gaussian noise plus subspace interference is addressed. It is assumed that the actual steering vectors lie along a fixed and unknown direction of a preassigned and known subspace, while ...

Machine Learning Doppler‐Tolerant One‐Bit Radar Detectors
Doppler‐tolerant waveforms are some of the most common radar waveforms used in practice. However, their deterministic and repetitive nature impedes control of mutual interference when multiple radars operate in close proximity. Noise radar technology may

Detection and Estimation of Abrupt Changes contaminated by Multiplicative Gaussian Noise [PDF]
The problem of abrupt change detection has received much attention in the literature. The Neyman Pearson detector can be derived and yields the well-known CUSUM algorithm, when the abrupt change is contaminated by an additive noise.
