We present an online method to estimate the number of radar emitters from sequential batches of detected pulses. To do this, we employ a recently developed Bayesian nonparametric clustering method that automatically infers the number of clusters in the data. Semiparametric change detection ensures accurate cardinality estimates in a dynamic signal environment where the number of emitters changes over time. This method improves upon the state of the art by providing better estimates of the number of clusters while processing pulses in an online fashion. We demonstrate its effectiveness on three simulated radar scenarios with increasing pulse density.
