چکیده
Abstract Frequency diverse array (FDA), which can be combined with Multiple-input-Multiple-output (MIMO) to improve the performance of system, and range information provided by FDA-MIMO radar provides a new idea for suppressing main lobe interference. However, periodicity angle-range two-dimensional beam pattern also causes some safety hazards beamforming process. When interference is located in grating radar, related algorithm will appear serious distortion. The traditional nonlinear frequency offset method remove cause problem large width. In this paper, log function proposed, not only achieve periodic removal but has narrower bandwidth 3dB compared

An Improved Adaptive Received Beamforming for Nested Frequency Offset and Nested Array FDA-MIMO Radar
For the conventional FDA-MIMO (frequency diversity array multiple-input-multiple-output) Radar with uniform frequency offset and uniform linear array, the DOFs (degrees of freedom) of the adaptive beamformer are limited by the number of elements. A better performance-for example, a better suppression for strong interferences and a more desirable trade-off between the main lobe and side lobe-can...
متن کاملPerformance Analysis of MIMO-Frequency Diverse Array Radar with Variable Logarithmic Offsets
Frequency diverse array (FDA) uses a small frequency increment at each antenna element to get a range, angle and time dependent beam pattern. Although linear frequency offset is used in most radar systems, nonlinear frequency offset is also very useful for analyzing FDA radar. A logarithmic frequency offsets based FDA (log-FDA) removes the inherent periodicity of FDA beam pattern to get a singl...

In this paper, we address the problem of carrier frequency offset (CFO) estimation for multipleinput multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. We reconstruct the received signal to form data model with multi-invariance property, and then multiinvariance MUSIC algorithm for CFO estimation is proposed. Our proposed algorithm has the better CFO estimation pe...

This paper addresses techniques of Radio Frequency Interference (RFI) suppression applied to Synthetic Aperture Radar (SAR) data. These techniques could also be used to protect radio-astronomical observations from harmful interference.

متن کاملCSSF MIMO RADAR: Low-Complexity Compressive Sensing Based MIMO Radar That Uses Step Frequency
A new approach is proposed, namely CSSF MIMO radar, which applies the technique of step frequency (SF) to compressive sensing (CS) based multi-input multi-output (MIMO) radar. The proposed approach enables high resolution range, angle and Doppler estimation, while transmitting narrowband pulses. The problem of joint angle-Doppler-range estimation is first formulated to fit the CS framework, i.e...
