Problems solved by technology

[0003] The waveform generation of modern radar systems usually adopts direct digital synthesis, including two different implementation methods based on phase accumulation and direct reading based on waveform storage. The types of waveforms output by the front end are usually fixed and limited, and the support for complex modulation patterns is not flexible. The latter has high real-time requirements for software calculation and data transmission, which increases the complexity of the radar system.

Abstract

The invention discloses an adjustment separation radar waveform generation method, device and equipment and a medium, and the method comprises the steps: giving a basic waveform library and modulation parameters, and enabling the basic waveform library to comprise a plurality of basic waveform vectors; a coherent processing interval is taken as a period, the number of pulses of a transmitted pulse string signal in one coherent processing interval is expressed as M, generation of each pulse in the pulse string signal is decomposed into two processes of basic waveform selection and pulse modulation, a basic waveform vector corresponding to each pulse is selected from a basic waveform library, and the basic waveform vector corresponding to each pulse is selected from the basic waveform library. And modulating a basic waveform corresponding to the basic waveform vector by using the modulation parameter to obtain a radar pulse signal to be transmitted at present. According to the method, any basic waveform vector can be selected from the basic waveform library in the radar waveform generation process, and the modulation of the basic waveform corresponding to the basic waveform vector is realized by using the modulation parameter. Compared with an existing method, the method has the advantages that the calculation amount and the transmission delay are reduced while any waveform is supported, a new scheme is provided for software radar waveform generation, and the requirements for flexible waveform transformation and waveform modulation are met.
