Abstract

The invention belongs to the field of radar signal processing, and particularly relates to a parallel radar pulse compression method which uses a real-time operating system for real-time scheduling. The parallel radar pulse compression method includes the steps that CPU affinity API functions set in a linux kernel are used for binding the progress for achieving a pulse compression algorithm to a certain kernel of a multi-kernel CPU, so that the kernel of the multi-kernel CPU only carries out the pulse compression algorithm, based on kernel binding, the operating system uses an improved real-time scheduling mechanism and ensures real-time processing of the pulse compression process without being affected by factors such as system interrupt, external interrupt and other progress operation, and therefore real-time performance of the system is greatly improved. The method effectively improves the implementation efficiency of the pulse compression algorithm, and radar signals can be processed in real time.

Description

technical field

[0001] The invention belongs to the field of radar signal processing, in particular to a parallel radar pulse compression method utilizing real-time scheduling of a real-time operating system. Background technique

[0002] The chirp signal is a signal form with a large time-band product, which can achieve a high range resolution while ensuring a certain signal transmission power, so it is widely used in radar systems. For the pulse compression process in the chirp signal, multiple Fast Fourier Transform Algorithm (FFT) transformations and multiple multiplication and accumulation operations are required, so the pulse compression algorithm is transplanted to the Graphics Processor (Graphics Processor). Processing Unit (GPU) parallel computing platform, using the GPU parallel computing method can improve the implementation efficiency of the pulse compression algorithm.
