摘要:Abstract(#br)This paper proposes a novel approach to robust radar detection of range-spread targets embedded in Gaussian noise with unknown covariance matrix. The idea is to model the useful target echo in each range cell as the sum of a coherent signal plus a random component th...

摘要:Abstract(#br)This paper deals with the radar detection of targets embedded in K-distributed clutter with partially correlated texture. A model for K-distributed clutter is first proposed, which is consistent with the main models of non-Gaussian scattering, and its generality is ...

摘要:Abstract(#br)The application of supervised learning machines trained to minimize the Cross-Entropy error to radar detection is explored in this article. The detector is implemented with a learning machine that implements a discriminant function, which output is compared to a th...

摘要:Abstract(#br)In this article we try to answer the question whether the radar detection technique can be used for the detection of high-energy-neutrino induced particle cascades in ice. A high-energy neutrino interacting in ice will induce a particle cascade, also referred to as a...

摘要:... According to the RCS (Radar Cross Section) characteristic of target, amplitude and phase modulation are made to acquire the signal having the same frequency as the echo pulse but with the opposite phase. This signal cancels the radar echo signal. The basic theory of active ca...

摘要:... On the other hand, the function approximated by a 2C-Support Vector Machine after perfect training is also a binary function, but this machine implements the Neyman–Pearson detector for a fixed probability of false alarm and probability of detection pair, that can be s...

摘要:Abstract(#br)We revisit the radar echo technique as an approach to detect ultra-high energy cosmic rays (UHECR). The UHECR extensive air showers generate disk-like ionization fronts propagating with a relativistic velocity and creating fast decaying plasma. We study the reflectio...

摘要:Abstract(#br)In this paper, we analyze the detection performance of non-coherent radar for correlated gamma fluctuating targets in K distributed sea clutter. We present the radar signal models at first. Then we derive the mathematical expression of the radar detection probability...

摘要:Abstract(#br)The time-varying, dispersion and non-stationary ionospheric characteristics cause the sky-wave radar echo spectra broaden and the layer-structure characteristics make the multimode and multipath propagation occur, which seriously affect the detection performance of t...

摘要:Abstract(#br)Reflection of radio waves off the short-lived plasma produced by the high-energy shower particles in the air is simulated, considering various radar setups and shower geometries. We show that the plasma produced by air showers has to be treated always as underdense. ...
