LIDAR Shot Reordering via Pseudorandom Dithering

The patent applies dynamics by transitioning from a static periodic light pulse schedule to a dynamic pseudorandom schedule. The shot dither component introduces variability in the timing between consecutive light pulses, making the emission pattern unpredictable while maintaining a defined average shot rate. This dynamic approach prevents range aliasing and interference by ensuring that temporally-adjacent shots do not follow a predictable pattern that could be exploited or cause measurement errors.

The patent applies parameter changes by carefully controlling the magnitude and distribution of the pseudorandom shot dither component. Rather than using a fixed large dither value, the system adjusts the dither parameters to achieve an optimal balance: the dither is large enough to prevent range aliasing and interference but small enough to maintain an acceptable shot rate. This involves tuning the pseudorandom delay distribution to ensure that the majority of shots remain closely spaced in time while still providing sufficient variability to mitigate aliasing.

The patent applies partial action by implementing a pseudorandom shot dither with controlled variability rather than maximizing the delay variation. The system uses a moderate level of pseudorandomness that provides sufficient protection against interference and attacks without requiring excessively long listening windows. This balanced approach ensures that the listening window remains short enough to maintain high shot rates while still providing adequate security and measurement accuracy.
