+The bistatic range displayed on the KrakenSDR range-doppler graph is described by the formula Rtx + Rrx - L

+# 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 c / fs = 299 792 458 / 2400000 = ~125m resolution per range cell on the graph.
