Cognitive Radar Waveform Optimization Based on Mutual Information and Kalman filtering [PDF]

open access: yesEntropy, 2018
A new strategy to optimizing the waveforms of cognitive radar under transmitted power constraint is presented. Our scheme is to enhance the performance of target estimation by minimizing the MSE (mean-square error) of the estimates of target scattering ...

A high doppler tolerance and low side-lobe NLFM waveform optimization method for SAR application [PDF]

open access: yesScientific Reports
The Non-linear Frequency Modulation (NLFM) waveform is known for its ability to reduce side-lobe levels without compromising the signal-to-noise ratio (SNR) or requiring windowing operations in Synthetic Aperture Radar (SAR) imaging missions. However, as

Colocated MIMO Radar Waveform-Array Joint Optimization for Sparse Array

open access: yesSensors, 2023
Colocated multiple-input multiple-output (MIMO) radar can transmit a group of distinct waveforms via its colocated transmit antennas and the waveform diversity leads to several advantages in contrast to conventional phased-array radar.

Optimal control theory with arbitrary superpositions of waveforms [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2014
Standard optimal control methods perform optimization in the time domain. However, many experimental settings demand the expression of the control signal as a superposition of given waveforms, a case that cannot easily be accommodated using time-local ...
