Chad Coulliette; ,; Francois Lekien; ,; Jeffrey ...Ultra-wideband (UWB) nonlinear frequency modulation (NLFM) waveforms have the advantages of low sidelobes and high resolution. By extending the frequency domain wideband synthesis method to the NLFM waveform, the synthetic bandwidth will be limited, and the grating lobe will grow as the number of subpulses increases at a fixed synthetic bandwidth. Aiming for the highly periodic grating lobes ...The state of the art in nonlinear radar is conveyed by presenting high-level system architecture, explaining the rationale behind design decisions pertaining to that architecture, and listing the ...

The radar was implemented in stepped frequency continuous wave mode with an output power of ≈50 dBm in the S-/C-band.intermodulation radar at 5.8 GHz ISM band and the passive tag were designed, fabricated and characterized. The motion and the intermodulation generated by the tag were measured, as compared with undesired fundamental reflections. This intermodulation-based nonlinear radar approach can overcome some drawbacks of harmonic radars. It has wide TMD Weather Radar. TMD Radar Loop. TMD Radar Composite. Bangkok Radar.

For passive bistatic radar target tracking problem, the performances of several nonlinear filtering algorithms such as EKF, UKF and CDF were simulated and analyzed.We propose nonlinear beamforming for phased array weather radars (PAWRs). Conventional beamforming is linear in the sense that a backscattered signal arriving from each elevation is reconstructed by a weighted sum of received signals, which can be seen as a linear transform for the received signals. For distributed targets such as raindrops, however, the number of scatterers is significantly ... ….
