Interaction of axisymmetrically-polarized (radially or azimuthally-polarized), relativistically intense laser pulses (ALP) with under-dense plasma is shown experimentally to be different from the interaction of conventional Gaussian pulses. The diffe

This paper proposes the fast chirp MIMO radar using Doppler offset orthogonal codes (DO-OCs). The proposed enables Doppler and code division multiplexing. The proposed has two merits. One is that phase modulators to modulate chirp signals is to be si

We propose a convolutional neural network (CNN)which classifies the type and direction of a stationary object from the range-Doppler map acquired by a 79 GHz MIMO radar. The multi-class (21 classes)classification is performed by inputting the single

This paper proposes fast 2D maximum likelihood (ML) angle estimation in order to reduce computational complexity and to enhance 2D angle separation ability. The proposed consists of two steps. The first step is independent 1D ML azimuth/elevation ang

For tracking multiple moving targets, a multi-radar system employing ultra-wideband millimeter-wave array antennas is introduced. To separate the multiple echoes and the different Doppler velocities of the targets, the frequency-domain interferometri
