Description

technical field [0001] The invention relates to a method for resource scheduling of a wide-beam frequency-variable time-difference positioning system, in particular to an implementation framework for resource scheduling of the wide-beam frequency-variable time-difference positioning system, adaptive generation of scheduling task parameters, task priority evaluation, and scheduling adaptive execution algorithms. Background technique [0002] Time difference positioning uses the time difference of the same radiation source signal to reach multiple stations to form a hyperbola (surface) for positioning. As a passive positioning technology, long-baseline time-of-flight positioning has been widely used in engineering because of its high positioning accuracy and simple positioning algorithm. [0003] Time difference positioning requires multiple stations to receive the same signal. Therefore, it is necessary to uniformly schedule the time, space, and frequency resources of multipl...

Problems solved by technology

[0005] The above method solves the resource scheduling problem of the time difference positioning system to a certain extent, but the resource scheduling method for integrated detection of IFF, TACAN, and radar signals for the wide beam frequency conversion time difference positioning system is still relatively lacking, and the related resource scheduling algorithm is mainly reflected in In terms of active detection, there are few studies on resource scheduling of multi-station wide-beam frequency-variable time-of-flight positioning systems, and related technical research is urgently needed
