Example Embodiment
[0034] Such as figure 2 As shown, this embodiment provides an integrated radar communication system, including a distance of R 2 Based on the pure radar system, the radar and control center considers the radar front to obtain the information gain. The detection process is the same as that of the ordinary radar system. The radar is used to transmit radio frequency signals. 1 (t), the distance is R 1 The target observation interval of the target observation interval is detected, and the echo signal reflected by the N targets in the target observation interval is received, and the position information is extracted from it and transmitted to the control center; the control center is used for data processing of the signal transmitted by the radar, Get the location of the target.
[0035] Among them, the echo signal reflected by the i-th target in the target observation interval received by the radar is:
[0036] r i (t)=α i s 1 (t-τ i )+n i (t),1≤i≤N
[0037] The received signal has expe...
