[0087] For LFM pulse radar signals, the input signal bandwidth of the receiver is about 5MHz, and the signal is sampled at a sampling rate of 10MHz. The parameters of target echo and interference are shown in Table 1.
[0088] Table 1 Delay simulation parameters
[0089]
[0090] Assume that the power of noise is σ 2 , The signal-to-noise ratio can be obtained based on the echo signal power and noise power, where the signal-to-noise ratio refers to the input signal-to-noise ratio with the echo signal bandwidth as a reference, and the signal-to-noise ratio is set as SNR.
[0091] A method for suppressing the same-frequency asynchronous interference of the same type radar in the case of ship formation, the specific implementation steps are as follows:
[0092] 1) Select 11 pulse repetition period data with a sampling rate of 10MHz / s and 10,000 points per period. Perform traditional pulse compression processing and MTD processing on these data. The processing results are as attached Fig...
