    Abstract
  • Pulse laser range detector is to measure the distance by estimating the time delay between the emitting pulse and echo pulse. In this paper, a mathematical model for the target echo signal of laser fuze has been established; in accordance with this model, the formulas for echo time-delay estimation and for amplitude estimation based on least squares criterion have been deduced. It is argued and simulated that the resolution of echo time-delay estimation could be improved through multi-reference correlation approach. Experiments illustrate that the approach enables pulsed laser fuze to perform high-precision ranging under a low signal-to-noise ratio condition.
