Abstract
Methods and apparatus to receive radar pulses, process the received pulses using weighted finite state machine to learn a model of an unknown emitter generating the received radar pulses, and estimate a state/function of the unknown emitter based on the received radar pulses using the learned model, and predict the next state/function of the unknown emitter based on the received radar pulses and applying maximum likelihood estimation.
Claims18
A method, comprising:
- receiving radar pulses from an unknown radar emitter at an input of a radar warning system;
- processing the received pulses using a weighted finite state machine implemented in the radar warning system to learn a model of the unknown radar emitter;
- storing the learned model in memory on the radar warning system;
- estimating, using a computer processor on the radar warning system, a state/function of the unknown radar emitter based on the received radar pulses using the stored learned model;
- and
- automatically building finite state machines using finite state transducers based on instructions stored in the memory.
