Directional Moving Target Indication: A Novel SAR Ambiguity Function for Traffic Monitoring

Figure 2

Two moving targets with different trajectories can induce the same phase on the received echoes 𝑠 1 ( 𝑢 ) and 𝑠 2 ( 𝑢 ) . However, the amplitude information of these signals can be used to remove this ambiguity.
