MATLAB

The program will take in 4 numbers representing the time in us of the

received pulse. The first two pulses are the transmitted pulses. For example, consider the

following pulse timings.

1862 1874 2024 2036

The spacing for the transmitted pulse is 1874-1860 = 12 us.

The spacing between the received pulses is 2036--2024 = 12us

This is a valid channel X transmission.

The time between when the first pulse was transmitted and received is 2024-1862 = 162us

This can be converted to distance by (162 50)/12.36 = 9.06 nmi.

TASK: Create a MATLAB function that takes in the time of 4 pulses.

If correct pulses for channel X are detected the system will print

Channel is X, distance is dd.d nautical miles.

Where dd.d is the correct distance such as 12.2.

If correct pulses for channel Y are detected the system will print

Channel is Y, distance is dd.d nautical miles.

Where dd.d is the correct distance such as 12.2.

If the system receives a valid pulse spacing for the X channel when transmitting on the Y

channel or vice versa, this means that we have received pulses from an aircraft other than our

own. In this case the system will print

FRUIT detected.

if the measured time between the transmitted and received pulses exceeds 200 nmi than the

system will print

Channel is X, no reply.

or

Channel is Y, no reply.

depending on the channel.

If incorrect pulses spacings for channel X or Y are detected or if the received signals arrive in

less than the built-in delay of the ground station print

Signal Garbled.
