MIMO radar space–time adaptive processing using prolate spheroidal wave functions [PDF]
, 2008 In the traditional transmitting beamforming radar system, the transmitting antennas send coherent waveforms which form a highly focused beam. In the multiple-input multiple-output (MIMO) radar system, the transmitter sends noncoherent (possibly ...

Impact of PRF design on GMTI performance of MIMO-SAR for hypersonic platform with curved trajectory
The Journal of Engineering, 2019 Compared with the conventional single-channel sampling or azimuth multichannel sampling of SAR system, the multiple-input multiple-output (MIMO) sampling has the potential to realise the high-resolution wide swath (HRWS) imaging and the ground moving ...

Open set HRRP recognition based on convolutional neural network
The Journal of Engineering, 2019 Most existing algorithms in high-resolution range profile recognition focus on the closed set cases, where the test sample is from a known class. However, a sample could be drawn from unknown classes in realistic scenario, which is named as open set ...

Super-Resolving Quantum Radar: Coherent-State Sources with Homodyne Detection Suffice to Beat the Diffraction Limit [PDF]
, 2013 There has been much recent interest in quantum metrology for applications to sub-Raleigh ranging and remote sensing such as in quantum radar. For quantum radar, atmospheric absorption and diffraction rapidly degrades any actively transmitted quantum ...

Information distances for radar resolution analysis
2017 IEEE 7th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2017 A stochastic approach to resolution based on information distances computed from the geometry of data models which is characterized by the Fisher information is explored. Stochastic resolution includes probability of resolution and signal-to-noise ratio (SNR).
