The present application discloses a linear frequency modulation signal generation method, device and storage medium. The method includes: receiving externally input frequency modulation slope quantization parameters and time width quantization parameters; determining based on the frequency modulation slope quantization parameters and the time width quantization parameters A waveform phase parameter corresponding to the chirp signal to be generated; determining real part data and imaginary part data corresponding to the chirp signal to be generated based on the waveform phase parameter and the stored sine-cosine lookup table. Since it only needs to receive FM slope quantization parameters and time width quantization parameters, it can reduce external input, reduce the number of control signal connections in hardware, and also help reduce system design complexity, especially suitable for application in spaceborne radars.
Description
technical field [0001] The present application relates to the technical field of signal processing, and in particular to a method, device and storage medium for generating a chirp signal. Background technique [0002] As a commonly used pulse compression signal in radar systems, chirp signal has been widely used in the field of high-resolution radar. In recent years, with the continuous development of radar technology, the improvement of system performance indicators, and the increase of working modes, the demand for radar transmission signals is also increasing. Traditional spaceborne radars can only generate several or more than a dozen chirp signals, which cannot meet the evolving system requirements. Contents of the invention [0003] In view of this, embodiments of the present application provide a chirp signal generation method, device, and storage medium, aiming at at least solving the problem that the generated chirp signal cannot meet system requirements.
