“…In this case, there must be some groups that do not contain effective signal components, and these groups do not contribute to SNRAA. According to this feature, AAE is introduced to represent the contribution of each group of data to the improvement in the accumulated SNR, which is defined as (15). The adoption of AAE aids in preventing the PSO algorithm from being entangled in the PRF harmonic component local optimization.…”

“…Based on the information obtained by ESM, effective electronic countermeasures (ECM) [10][11][12] can be easily generated to counter specific radar sources. However, with the iteration and development of radar technology, low probability interception (LPI) [13][14][15][16][17] radar is widely used in practice, which makes the signal power lower than before. Moreover, it is difficult to guarantee that the ESM receiver is arranged in hostile radar's main lobe irradiation areas.…”

“…However, this approach cannot sufficiently reflect the characteristics of non-stationary signals. In fact, most stochastic processes, including radar navigation signals [1], satellite signals [2], sonar signals [3] and so on are non-stationary in nature [4]. It is therefore vital to extract the characteristics of non-stationary signals with the objective of developing signal processing methods that are more appropriate for the representation, analysis, and processing of said signals.…”
