Abstract

The embodiment of the invention provides a cognitive frequency-agile radar waveform design method and device. The method comprises the steps that according to received frequency-agile radar baseband echo signals, observation data is obtained; and according to the observation data, initial values of carrier frequency code words of to-be-emitted waveform signals are iterated till the carrier frequency code words, meeting preset conditions, of the to-be-emitted waveform signals are obtained. According to the cognitive frequency-agile radar waveform design method and device in the embodiment, sequential batch processing is performed on echo signals of a plurality of batches of emitted waveform signals to obtain the observation data, and according to the observation data, the initial values ofthe carrier frequency code words of the next batch of to-be-emitted waveform signals are iterated to obtain the carrier frequency code words of the next batch of to-be-emitted waveform signals. In this way, mutual interference among all target echoes can be effectively relieved, therefore, cognitive design of the frequency-agile radar waveform signals can be realized, and cognitive frequency-agileradar waveform design can be realized through sequential batch processing.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of signal processing, and in particular to a waveform design method and device for a cognitive-agile frequency radar. Background technique [0002] Coherent frequency-agile radar (coherent frequency-agile radar) is a pulse system radar, the carrier frequency of each radar pulse can be switched randomly and quickly within the entire bandwidth of the radar. The coherent pulse sequence can accurately record the radar echo phase change caused by the change of the pulse carrier frequency and the relative position of the target, making it possible to synthesize high-resolution range images and realize Doppler processing through coherent accumulation between pulses. Because the carrier frequency of frequency-agile radar has the characteristic of random change, it has superior performance in the fields of electronic countermeasures and electromagnetic compatibility.
