Online task interleaving scheduling for the digital array radar

Variable scheduling interval task scheduling for phased array radar

“…The whole simulation frame is established based on references [8,20,21]. In simulations, set t SI = 50 ms, P τ max = 1.25 kW, τ = 200 ms, t SI min = 25 ms, t SI max = 100 ms, S ex = 4.…”

“…(i) The successful scheduling ratio (SSR), which is the ratio between the number of all successfully scheduled tasks N suc and that of all request tasks N total . The SSR [7,11,12,18,20,21,25,26] can be expressed as…”

Phased-Array Radar Task Scheduling Method for Hypersonic-Glide Vehicles

“…If there are available remaining radar resources, go to step (8); otherwise, go to step (9). (8) Calculate the number of search tasks that can be added based on the amount of remaining radar resources. Add the search tasks to the formal scheduling task request queue.…”

“…Therefore, this paper considers mainly the time resource constraints of radar task scheduling. To quantify the effect of the task overlap on the objective function when the radar task competes for the same time slot, the penalty function is introduced into the objective function, and the penalty function is calculated as shown in formula (8). The quantization function of the task dwell overlap time is taken as the probability density function of the unilateral normal distribution.…”

“…According to the threat level of the target, references [6], [7] used a three-way decision method to divide the target into threat targets, nonthreat targets, and potential threat targets, and set different dwell times for each type of target to improve the time resource utilization rate of radar task scheduling. References [8]- [10] made full use of the waiting period between the transmitting pulse and receiving pulse of the phased-array radar, and designed a pulse interleaving scheduling algorithm, which improves the time resource utilization and scheduling success rate of the radar. Reference [11] pointed out that in the process of multitarget tracking, there is a linear relationship between the emission energy of the radar and the dwell time, and the nonconvex optimization problem of energy and time distribution can be transformed into a standard convex optimization problem.…”
