Abstract

This invention provides a target detection method, apparatus, electronic device, and storage medium. The method includes: acquiring echo data received by a vehicle-mounted radar; performing a Fast Fourier Transform (FFT) on the echo data to obtain range-Doppler two-dimensional data; and performing detection processing on the range-Doppler two-dimensional data according to a preset pre-detection tracking model to obtain a target detection result. The preset pre-detection tracking model includes at least a particle filter-based pre-detection tracking model. The preset pre-detection tracking model employs a first preset likelihood ratio function, which includes a background noise amplitude term and a sum term of the target's amplitude and the background noise amplitude. Using this invention can reduce the computational resources consumed by particle filter-based pre-detection tracking algorithms for target detection, thereby reducing its computational cost.
