A ranging method includes determining a pixel matrix based on a received echo signal, determining a first amplitude value set based on a first pixel, determining a second pixel based on the first pixel, determining, based on the second pixel, a second amplitude value set based on the second pixel, performing a summation on a target first amplitude value set and a target second amplitude value set, obtaining a target ranging set based on all first amplitude value sets and all second amplitude value sets, and performing a ranging based on the target ranging set to improve a signal-to-noise ratio of an accumulated amplitude value set and a ranging accuracy.

Ranging method, radar, and vehicle-mounted radar

A method includes: determining, a first pixel in a receiving field of view of a radar and N sampling point sets in an echo signal corresponding to the first pixel; estimating an estimated distance between the radar and a target object based on each first sampling point set of the N sampling point sets, and determining, based on each estimated distance, M cumulative receiving fields of view in a one-to-one correspondence with M data frames; determining a second sampling point set in echo signals corresponding to Q neighboring pixels, and superposing each first sampling point set and the corresponding second sampling point set to obtain an echo signal that corresponds to the first pixel and that is obtained; and calculating an actual distance between the radar and the target object based on the echo signal obtained after superposition processing.
