- Abstract
In the enhanced technology field of signal-to-noise ratio(SNR) as a signal quality index, aiming at the problem of how to estimate the SNR of radar signals with complex overlapping quickly and accurately, the subspace decomposition algorithm is improved, and Particle Swarm Optimization(PSO) algorithm which is simple in structure and fast in iteration is introduced to solve the autocorrelation matrix eigenvalue. The effectiveness of the algorithm is verified by setting different electromagnetic environment scenarios. Comparative analysis shows the obvious advantage of the algorithm under the condition of low SNR, which provides a strong support for testing the effect of signal enhancement technology.
