Clutter Rejection for FM Ranging Airborne Radar [PDF]
Journal of Electromagnetic Engineering and Science, 2023 In airborne radar, it is important to reject clutter signals to detect targets of interest. High pulse repetition frequency (HPRF) waveform provides robust detection performance in a clutter environment by separating clutter signals from the target echo ...

How Much Depth Information can Radar Contribute to a Depth Estimation Model? [PDF]
, 2022 Recently, several works have proposed fusing radar data as an additional perceptual signal into monocular depth estimation models because radar data is robust against varying light and weather conditions. Although improved performances were reported in prior works, it is still hard to tell how much depth information radar can contribute to a depth ...

Unambiguous range extension for pulse‐Doppler radar via Poisson disk sampling
IET Radar, Sonar & Navigation, 2021 Since the maximum unambiguous range in the traditional single‐channel pulse‐Doppler (PD) radar is restricted by the pulse repetition interval (PRI), there is a trade‐off between the maximum unambiguous range and the maximum unambiguous velocity.

White noise jammer mathematical modelling and simulation [PDF]
, 2020 The radar equation is the fundamental mathematical modelling of the basic function of a radar system. Moreover there are many versions of the radar equation that correspond to particular radar operations, like a low PRF, a high PRF or a surveillance mode.
