Three dimensional random matrix radar frequency hopping function model and its application

Abstract： In complex and harsh electromagnetic environment, radar will be interfered, resulting in unrecognizable target or target loss. Frequency hopping is an effective measure to deal with electronic interference from enemy or natural environment. Frequency hopping methods include blind hopping, pseudo-random frequency hopping and adaptive frequency hopping. Aiming at adaptive frequency hopping technology, a three-dimensional random matrix adaptive frequency hopping algorithm is proposed. Firstly, the time set matrix, the frequency point interference amplitude set matrix, and the available frequency point set matrix are established. On the basis of these, the three-dimensional random matrix mathematical model is generated, and then the implementation method is given. Combined with practical engineering applications, the effectiveness of the algorithm is verified. The results show that the algorithm improves the pulse compression ratio of radar to a certain extent, greatly improves the anti-jamming ability of radar in electromagnetic environment, and is of great significance to improve the radar target recognition ability.
