Question

For the ionospheric model in Problem 7.5, calculate the differential delay at the opposite extremes of the transmitted frequency spectrum for a wave with center frequency 12.4 GHz and with a bandwidth of 400 MHz.

Problem 7.5

Assuming that the variation of electron density with height is as

Show that the total electron content N_T = N_o/K. Evaluate N_T for N_o = 10¹³ per cubic meter and K-1 = 10 km.
