Nonlinear radar
Aiming at high-resolution radar target recognition, new convolutional neural networks, namely, Inception-based VGG (IVGG) networks, are proposed to classify and recognize different targets in high range resolution profile (HRRP) and synthetic aperture radar (SAR) signals. The IVGG networks have been improved in two aspects. One is to adjust the connection mode of the full …In this paper, a new nonlinear radar is designed based on the principle of intermodulation to separate clutter from the target of interest. This intermodulation radar can overcome some drawbacks of harmonic radars. Its 3rd-order tones are close to the fundamental tones, sharing almost the same path loss as the Because a typical Schottky diode weighs less than 1/4 of a gram and requires no external power to be visible to nonlinear radar, it is a frequent choice for the nonlinear element in tags carried ...
