AB  - In this paper, we consider a chirp spread spectrum (CSS) transceiver and jamming model and design an algorithm for chirp-based wireless localization precision enhancement in an electronic warfare environment. The algorithm uses the processing gain of the chirp band spread spectrum and the correlation characteristics of the preamble to improve the ranging performance from a low sampling rate converter, and then applies it to a typical wireless localization algorithm and analyzes its performance through simulations in various environments.
