Incoherent scattering radar
WebThe standard analysis of Barker-coded incoherent scatter experiments is based on a matched filter with an im- pulse response which is a mirror image of the code itself. The method produces small sidelobes which cause contamination from regions outside the nominal range gate. WebEnter the email address you signed up with and we'll email you a reset link.

WebJul 11, 2002 · In the European Incoherent Scatter (EISCAT) Svalbard Radar (ESR), which is located on Svalbard within the polar cap, the signal is down-converted to 7.5 ± 1.9 MHz passband in two stages and sampled at a rate of 10.0 MHz. Then the receiver branches out into six parallel digital channels. WebApr 11, 2024 · In such cases, incoherent components should be used to estimate the roughness. As it has been presented in Section 4.1, the coherent component and the total power waveform present a ~−9 dB consistent bias and an ubRMSD of 3.4 dB. Computing the roughness with coherent or incoherent components might impact a bias in the retrieved …
