Adaptive Dwell Scheduling Based on a Novel Online Pulse Interleaving Technique for Phased Array Radar

Real‐time dwell scheduling algorithm for phased array radar based on a backtracking strategy

“…To improve the time utilisation of the dwell scheduling, pulse interleaving is considered. By combining the dwell scheduling algorithm with pulse interleaving based on the time pointer [14] and above motivation of backtracking, the proposed realtime dwell scheduling algorithm for phased array radar based on the backtracking strategy is obtained. Suppose N tasks Τ ¼ ½T 1 ; T 2 ; …; T N � are applied to be scheduled in the SI ½t 0 ; t 0 þ t SI � and the specific steps of the proposed algorithm are listed as follows:…”

“…The adaptive dwell scheduling algorithms can be further divided into the ones based on the heuristic method [5][6][7][8][9][10][11][12][13][14] and the ones based on the intelligent method [15][16][17][18][19][20][21][22][23][24][25][26][27]. A dwell scheduling algorithm based on time pointer is proposed in ref.…”

“…For example, although the ones in refs. [5][6][7][8][12][13][14] can execute as many highpriority tasks as possible, the bias between the actual execution time and the desired execution time is very high. On the contrary, the ones in refs.…”

“…To realise the effective and efficient allocation of limited resources among various tasks, the real‐time dwell scheduling for PAR must be studied. Dwell scheduling for PAR has been extensively studied nowadays, which can be divided into two types: template‐based dwell scheduling algorithms [2–4] and adaptive dwell scheduling algorithms [5–27], where the latter ones have better performance because the templates designed offline cannot match with actual online task load.…”

“…In ref. [14], the time and energy vectors are introduced in the dwell scheduling algorithm based on pulse interleaving, which allows dwell tasks with different PRI and pulse repetition numbers to be interleaved.…”
