 # Range Resolution
 Range resolution depends on the sampling bandwidth, which for the KrakenSDR and RTL-SDR tuners inside is 2.4 MHz. Therefore we achieve $\frac{c}{fs} = \frac{299792458}{2400000} = ~125m$ resolution per range cell on the graph (assuming the illuminating signal is at least 2.4 MHz as well).
 
-This means that we can differentiate between two different objects that are 125m apart.

+This means that we can differentiate between two different objects that are 125m apart. Or in other words, two objects closer than 125m apart will be combined into a single range cell.
+
+Another example, if we are using a DAB transmitter as the illuminator, then we only have 1.5 MHz of bandwidth. Therefore we achieve $\frac{c}{fs} = \frac{299792458}{1500000} = ~200m$ resolution per range cell.
