For the 2D radar system, in order to improve the performance of target plots, a new algorithm based on geometric center and amplitudes of measurements was proposed, aimed at that the traditional plots centroid algorithm does not use the amplitude information or over-uses it. The proposed algorithm can reduce the weights of the measurements which are far away from the geometric centre, so as to obtain...
A chaotic detection scheme for a small-sized range-spread target in white Gaussian noise is developed. The basic idea is that a chaotic oscillator system is less influenced by noise, but it is very sensitive to periodic or pseudo-periodic signals. Firstly we concatenate the echoes with the same interested range cells from three successive pulses transmitted by high resolution radar end to end into...
Based on modulated frequency stepped signal model, the interference phase which impacts the precision of the least burst error velocity measure method is analyzed in this paper, phase correction factor is given to improve the accuracy of the least burst error velocity measure method for moving targets, finally the signal processing flow is given and the performance is verified by computer simulation.
