[0024] Reference figure 1 , Is a flow chart of an adaptive detection method for radar signals based on an autoregressive model of the present invention; the adaptive detection method for radar signals based on an autoregressive model includes the following steps:
[0025] Step 1. The radar receives the coherent pulse sequence of N pulses, and uses the coherent pulse sequence of N pulses as the target unit echo z 0 ,z 0 ∈ C N×1 , ∈ means belonging, C N×1 Denotes an N×1 dimensional complex vector, the N×1 dimensional complex vector is expressed as the complex value of the coherent pulse sequence of N pulses received by the radar, and then the detection problem of the radar on the target is expressed by a binary hypothesis test:
[0026] Where H 0 The echo of the target unit to be detected z 0 Only interference hypothesis, H 1 The echo of the target unit to be detected z 0 The assumption of target and interference exists in, p represents the steering vector of the N pulse coherent pul...
