Optimal Mismatched Filter Design by Combining Convex Optimization With Circular Algorithm
IEEE Access, 2022 Mismatched filters (MMF) have been intensively explored for linear-frequency modulation (LFM) waveform sidelobe reduction. Unlike other design strategies, the use of convex optimization (CO) techniques is able to find the optimal design.

Sidelobe suppression for phase-coded pulse by mainlobe windowing
The Journal of Engineering, 2019 Mismatched filter is an important technique to suppress the sidelobes of phase-coded pulses. Here, the authors propose a mainlobe windowing procedure, by which a much lower sidelobe level can be obtained at a slightly signal-to-noise ratio loss. Based on

Peak Sidelobe Level Reduction With a Hybrid Approach Based on GAs and Difference Sets [PDF]
IEEE Transactions on Antennas and Propagation, 2004 This paper presents an approach for the optimization of the beam pattern produced by massively thinned arrays. The method, which combines the most attractive features of a genetic algorithm and those of a combinatorial technique (namely, the difference sets method), is aimed at synthesizing massively thinned antenna arrays in order to suitably reduce ...

Doppler Shift Tolerance of Typical Pseudorandom Binary Sequences in PMCW Radar
Sensors, 2022 In the context of all-digital radar systems, phase-modulated continuous wave (PMCW) based on pseudorandom binary sequences (PRBSs) appears to be a prominent candidate modulation scheme for applications such as autonomous driving.
