This paper presents a system model and method for the 2-D imaging application via a narrowband multiple-input multiple-output (MIMO) radar system with two perpendicular linear arrays. Furthermore, the imaging formulation for our method is developed through a Fourier integral processing, and the parameters of antenna array including the cross-range(More)
Imaging a fast maneuvering target has been an active research area in past decades. Usually, an array antenna with multiple elements is implemented to avoid the motion compensations involved in the inverse synthetic aperture radar (ISAR) imaging. Nevertheless, there is a price dilemma due to the high level of hardware complexity compared to complex(More)
In this paper we propose an imaging method via wideband multiple-input multiple-output radar to reduce the hardware complexity of the system. Since a spatial parallel procedure to sample the scattered echoes during a single snapshot illumination, instead of the spatial sequential sampling procedure during multiple snapshot illuminations in classical ISAR(More)
Estimating motion parameters of the maneuvering target is a difficult thing currently for most of airborne synthetic aperture radar (SAR) due to the complex motion, which usually results into a defocus-blurred SAR image of the target. To avoid the difficulty, this paper proposes a high-resolution imaging method via airborne multiple-input and(More)
Target identification has been an active researching area in past decades. In this paper, we present an identification method based on the high-resolution image from a narrowband multiple-input multiple-output (NMIMO) imaging radar system. Different from the traditional image-based method, the key idea of the proposed method is to build the(More)
This paper presents a system model and method for the two-dimensional (2-D) imaging application via a narrowband multiple-input multiple-output (MIMO) radar system with two perpendicular linear arrays. The proposed method utilities the spatial parallel procedure sampling the scattered echoes during a single snapshot illumination, instead of the spatial(More)
MIMO (multiple-input and multiple-output) radar with OFDM (orthogonal frequency-division multiplexing) waveform, i.e., OFDM-MIMO radar, transmits diverse carrier frequency narrowband signals, which can be synthetized to a wideband one to improve the resolution via a method in this paper. We firstly establish the echo model of OFDM-MIMO radar, and then(More)
