Monopulse forward-looking imaging algorithm based on Levenberg–Marquardt optimisation
With precise angle measurement, traditional monopulse techniques for forward-looking imaging can acquire exact angle information of one single target within a radar beam. However, when multiple targets exist in a beam, it is difficult to resolve them. To
