A plan to establish a strategic command in the Republic of Korea has been announced recently. Commensurate strategic intelligence must be achieved to efficiently operate strategic assets. Signal intelligence (SIGINT) that collects invisible electromagnetic spectrum and produces strategic intelligence, and electromagnetic spectrum operations (EMSO) that conducts military operations based on the provided strategic intelligence are closely related to utilizing the electromagnetic spectrum. From this perspective, establishing the relationship between EMSO and SIGINT and developing a SIGINT strategy in an EMSO environment are currently critical issues when a strategic command establishment is planned, as SIGINT is a strategic tool. In this paper, we propose a SIGINT strategy in an EMSO environment to secure the initiative of the electromagnetic spectrum in modern and future warfare.

Estimation of interleaver parameter from scant received data has recently been researched. In this paper, we propose an improved algorithm for blind estimation of interleaver parameter using matrix multiplication under the condition of scant received data. First, we generate a matrix from the received data and make arbitrary square submatrices by randomly deleting rows and columns from the generated matrix. We then compose additional square matrices by multiplying the square submatrices, and examine the rank deficiencies of the additional square matrices. Finally, we blindly estimate the interleaver parameter based on the average rank deficiency of the additionally composed square matrices. Through computer simulations, we validate the proposed algorithm in terms of detection probability and the number of false alarms, and show that the proposed algorithm outperforms conventional ones.
