The invention discloses a
pulse Doppler radar detection and communication integrated waveform design method. The method has
covert communication and good precision. According to the technical scheme, information modulation and
time synchronization are achieved through intentional modulation of a
pulse Doppler radar repetition period and change of repetition frequency between pulse groups; a communication
receiver intercepts an OFDM
frequency spectrum embedded in
broadband noise,
data demodulation is achieved by extracting parameters, the
receiver transmits a waveform in a data response pulse segment, a transmitted
signal falls in a
processing time window of a detection
radar, pulse of a
frame synchronization pulse segment is subjected to pulse group M2 repetition period
estimation and initial position synchronization, and the data response pulse segment is subjected to pulse group M2 repetition period
estimation and initial position synchronization to realize reverse
asynchronous data transmission between the detection
radar and the receiving terminal, and the data and a corresponding
processing time window are predicted. In the
signal receiving process of the receiving terminal, information is extracted through
signal processing equipment, and fusion based on
radar communication integration is carried out from the aspects of hardware and waveforms.
