During the observation of micromotion targets in space, inverse synthetic aperture radar
usually obtains the narrowband and wideband echoes simultaneously. In order to exploit …

Except for the slight difference of micromotion parameters, some decoys and warheads have
the same geometry and micromotion form. As a result, recognition of similar space cone …

Narrowband and wideband waveforms are usually adopted simultaneously during the
observation of micro-motion space targets by inverse synthetic aperture radar (ISAR), which …

An effective method for identifying inertia characteristics of cone-shaped space target based
on deep learning is proposed. The inertia ratio is determined by the time-varying scattering …

High-resolution range profile (HRRP) sequences have great potential for space target
classification because they can provide both scattering information and micromotion …

The micro-Doppler phenomenon in the echo signal received from a ballistic target (BT) with
micro-motion is commonly used to discriminate BTs such as warheads and decoys. The joint …

For real-time target classification, a study was conducted to improve the AI-based target
classification performance using RCS measurements that are vulnerable to noise, but can …

Interrupted-sampling repeater jamming (ISRJ) is coherent jamming based on digital radio
frequency memory (DRFM) device, which repeatedly samples, stores, modulates, and …

In recent years, with the rapid increase in the number of drones, the abuse of drones for
activities such as terrorist attacks is bound to pose a threat to public safety and privacy …

There are a number of targets in space that are similar in shape, but they pose different
threat levels. It is necessary to discriminate these targets for the sake of space security. The …
