PRI agile radar target parameter estimation method based on capon algorithm

The invention belongs to the technical field of radar signal processing, and particularly discloses a PRI agile radar target parameter estimation method based on a capon algorithm, and the method comprises the steps: enabling a PRI agile radar to transmit a signal and receives an echo signal; performing frequency mixing processing and pulse compression processing on the radar echo signal and the corresponding transmitting carrier frequency in sequence to obtain an echo signal after pulse compression; designing a filter corresponding to the capon algorithm, and enabling the carrier frequency component contained in the echo signal input into the filter after the pulse pressure to completely pass through the filter, wherein the average output power of the filter is the minimum, and the minimum average output power serves as capon power spectrum estimation of the echo signal; and determining distance and velocity information for each target. According to the method, the frequency characteristic sidelobe can be mi
