Abstract. The problem of Markov optimal space-time processing in multichannel observation, which includes detections and evaluation as special cases, is considered and analyzed. It has been shown that with known statistics of signals and interference, the optimal multi-channel observation algorithm is equivalent to the optimal filter for single-channel observation. A technique is proposed for obtaining potential characteristics of multichannel reception with arbitrary signals, if characteristics are known during their single-channel reception.

Key words: space-time processing, multichannel observation, optimal filtering, Markov process, information parameter, potential characteristic, equivalent noise.

Financing: The work was carried out at the expense of the State Assignment ΉFSFZ-2024-0006.
