Sparse Representation Denoising for Radar High Resolution Range Profiling
Radar high resolution range profile has attracted considerable attention in radar automatic target recognition. In practice, radar return is usually contaminated by noise, which results in profile distortion and recognition performance degradation.

MIMO radar array design based on unequal subarrays
The idea of dividing the transmitting array of MIMO radar into unequal subarrays was proposed in the paper. This kind of MIMO radar obtains the coherent processing gain and the waveform diversity gain which the MIMO radar with equal subarrays (called it ...

Eigenvalue Adjustment-Based STAP in Airborne MIMO Radar Under Limited Snapshots
The covariance matrix performs a vital role for space-time adaptive processing (STAP) in airborne multiple-input multiple-output (MIMO) radar. As is known, the clutter-plus-noise covariance matrix (CPNCM), reflecting the statistical characteristics of ...

Rao and Wald Tests for Moving Target Detection in Forward Scatter Radar
This paper deals with adaptive moving target detection for a forward scatter radar in complex Gaussian noise. The echoes received by the forward scatter radar include not only the noise and the possible target signals but also the direct signals.

Joint transceive beamforming for multistatic radar system by semi‐definite relaxation method
The joint transmit and receive beamforming algorithm has been envisioned to optimise the target's signal‐to‐interference‐plus‐noise ratio by co‐designing the transmit and receive beamforming vectors simultaneously.
