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 ...

Knowledge-aided Bayesian covariance matrix estimation in compound-Gaussian clutter [PDF]
, 2010 We address the problem of estimating a covariance matrix R using K samples zk whose covariance matrices are kR, where k are random variables. This problem naturally arises in radar applications in the case of compound-Gaussian clutter. In contrast to the

Examination of the effect of array weighting function on radar target detectability [PDF]
, 2010 This paper describes a methodology to assess the detectability of targets by anairborne fire control radar operating in a medium PRF mode in the presence of strongground clutter as a function of the transmitting and receiving antenna array ...

Terahertz High-resolution Radar Clutter Measurement and Analysis
Leida xuebao, 2015 The clutter characteristics of terahertz high-resolution radar are essential for terahertz radar detection. This study analyzes the traditional clutter probabilistic model and the corresponding parametric estimation methods.

Modeling the Amplitude Distribution of Radar Sea Clutter [PDF]
Remote Sensing, 2019 Ship detection in the maritime domain is best performed with radar due to its ability to surveil wide areas and operate in almost any weather condition or time of day. Many common detection schemes require an accurate model of the amplitude distribution of radar echoes backscattered by the ocean surface. This paper presents a review of select amplitude

Statistical Analysis of Clutter for Passive Radar on an Airborne Platform
, 2022 S.412-417A statistical analysis of clutter distribution supports the design and informs the performance of radar system. While extensive work on clutter statistics from monostatic radar systems has been performed, statistical analysis of passive bistatic
