specific Embodiment approach 1

[0064] Specific implementation mode 1. Combination figure 1 This embodiment will be described. A behavior identification method for a frequency hopping communication radiation source described in this embodiment, the method specifically includes the following steps:

[0065] Step S1, at the transmitting end, after the information data to be transmitted by the frequency hopping communication radiation source is subjected to channel coding, digital modulation is performed on the coding result to generate a modulated signal;

[0066] The frequency synthesizer is controlled by the frequency hopping sequence generator to synthesize the local oscillator signal;

[0067] The modulated signal is mixed with the local oscillator signal to obtain the transmitted signal s whose frequency hops with time t (t), then filter the transmitted signal, and filter the filtered signal s t '(t) is transmitted to the channel;

[0068] The signal reaches the receiver through the transmission of th...

specific Embodiment approach 2

[0077] Embodiment 2: This embodiment is different from Embodiment 1 in that the signal received by the receiver is:

[0078]

[0079] Among them, J(t) is the interference of other frequencies, n(t) is the noise, s j (t) is the frequency hopping communication signal transmitted by other network stations in the frequency hopping communication system, t is the time, and j represents the jth network station.

[0080] Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0081] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the specific process of step S21 is:

[0082] Step S211, based on the demodulation result and cyclic autocorrelation, to the intermediate frequency signal s after de-hopping p (t) The corresponding frame length is estimated;

[0083] Step S212: Accumulate the demodulation results in units of frame lengths to implement frame structure analysis.

[0084] The analysis of the frame structure is based on the similarity of the frame structure in each frame and the similar content of the frame header.

[0085] Other steps and parameters are the same as in the first or second embodiment.
