AbstractAutomatic modulation classification is essential in radar emitter identification. We propose a cascade classifier by combining a support vector machine (SVM) and convolutional neural network (CNN), considering that noise might be taken as rad

In practical bistatic inverse synthetic aperture radar (ISAR) imaging systems, the echo signals are modulated by non-ideal amplitude and phase characteristics of the transmitting and receiving channels, which seriously distorts image quality. However

The performance of both autofocusing and imaging resolution degrades using the traditional autofocusing and range–Doppler algorithm for bistatic inverse synthetic aperture radar (Bi-ISAR) with sparse apertures. A Bi-ISAR sparse imaging algorithm ba

The linear-geometry distortion and image defocus are induced by the time-varying bistatic angle in a bistatic inverse synthetic aperture radar (Bi-ISAR) system. Here, a distortion mitigation algorithm of a space target is proposed via exploiting the

Due to the large size of space targets, migration through resolution cells (MTRC) are induced by a rotational motion in high-resolution bistatic inverse synthetic aperture radar (Bi-ISAR) systems. The inaccurate correction of MTRC degrades the qualit

Aiming at the problems of poor ISAR imaging quality and long computation time with sparse apertures, a high resolution imaging algorithm based on fast sparse Bayesian learning is proposed. Firstly, an imaging model with sparse apertures based on comp
