Frazer Figure 7. (a) Single Channel Response showing four propagation modes. The peaks of the four propagation modes are marked with white circles, the units are Doppler (Hz) on the horizontal axis and radar range (km) on the vertical axis, and the intensity units dBJu are dB Joules uncalibrated. (b) and (c) Two range-Doppler maps show the effect of the adaptive transmitter processing for different mode selection for the multiple modes shown in (a). DECEMBER 2017 Figure 8. (a) Single Channel Response showing three propagation modes. (b) and (c) A series of range-Doppler maps showing the effect of the adaptive transmitter processing for different ranges.
