Surface Clutter Suppression Techniques for Ice Sounding Radars: Analysis of Airborne Data [PDF]
, 2008 For the ice sounding of Antarctica from space, a P-band radar at 435 MHz is the only option which complies with present ITU regulations. At this frequency the ice surface cannot be considered smooth, leading to high ambiguous returns.

Detection of moving radar targets in clutter
Information and Control, 1958 The moving target indicator is investigated for threshold power and visibility in clutter. In search for improvements, electronic scanning of the antenna beam is proposed and a detector is considered combining more than two pulses at a time.

Transductive Radar Clutter Segmentation Network for Ionospheric Inhomogeneity Clutter Suppression
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingThe ionosphere turbulent motions, detected by radar systems, result in a complex form of ionospheric inhomogeneity clutter. In this article, we introduce transductive radar clutter segmentation network (TRCS-Net), a deep unfolding network architecture ...

Clutter modelling and simulation for hypersonic vehicle-borne radar
The Journal of Engineering, 2019 Hypersonic vehicles (HSV) have attracted much attention in recent years because of its military value. The radar system will face more serious clutter problem due to the increasing altitude and velocity.

Advanced multipath clutter cancellation in OFDM-based passive radar systems
, 2022 4 S.We present an advanced algorithm to suppress multipath clutter in passive radar systems using OFDM signals for surveillance. Multipath clutter signals not only lead to enormous zero Doppler signals in the range Doppler domain, they also induce ...
