Purity of generalized affine Springer fibers from generic planar curve singularities Open
We prove the cohomological purity of punctual Hilbert schemes of points on generic irreducible planar curve singularities, by constructing an explicit affine paving. Via their identification with generalized $GL_N$-affine Springer fibers a…

Integral cohomology of dual boundary complexes is motivic Open
In this note, we give a motivic characterization of the integral cohomology of dual boundary complexes of smooth quasi-projective complex algebraic varieties. As a corollary, the dual boundary complex of any stably affine space (of positiv…

Radar Accurate Localization of UAV Swarms Based on Range Super-Resolution Method Open
In radar accurate localization of unmanned aerial vehicle (UAV) swarms, the high density, similar motion parameters, small radar cross-section (RCS), strong noise and far range put forward high requirements on radar resolution and transmit…

Reference Beam Pattern Design for Frequency Invariant Beamforming Based on Fast Fourier Transform Open
In the field of fast Fourier transform (FFT)-based frequency invariant beamforming (FIB), there is still an unsolved problem. That is the selection of the reference beam to make the designed wideband pattern frequency invariant (FI) over a…

Radar high-speed maneuvering target detection based on joint second-order keystone transform and modified integrated cubic phase function Open
Long-time coherent integration is an effective means to improve the radar detection ability of high-speed maneuvering targets with jerk motion. However, the range migration (RM) and Doppler frequency migration (DFM) have a great impact on …

Inverse synthetic aperture radar imaging of targets with complex motion based on the local polynomial ambiguity function Open
In inverse synthetic aperture radar (ISAR) imaging of targets with complex motion, the azimuth echoes have to be modeled as multicomponent cubic phase signals (CPSs) after motion compensation. For the CPS model, the chirp rate and the quad…

Three-dimensional interferometric inverse synthetic aperture radar imaging of maneuvering target based on the joint cross modified Wigner-Ville distribution Open
Inverse synthetic aperture radar (ISAR) can achieve high-resolution two-dimensional images of maneuvering targets. However, due to the indeterminate relative motion between radar and target, ISAR imaging does not provide the three-dimensio…

Novel design of Doppler resilient complete complementary sequence for MIMO radar Open
Complete complementary sequence (CCS) has ideal correlation performance along the zero Doppler axis. However, its correlation property is extremely sensitive to the Doppler shift. In this letter, by employing a sequential quadratic program…
