Choose the Millstone Misa ISR in single pulse 480 microsecond mode.
Run for 24 hours during Jan. 1st using 240 seconds of integration at 90 degrees elevation.
Determine how many seconds you can reduce the integration period to and still have less than 10% error at all times at 500 750 km altitude.
Describe what happens when the integration period gets short (1 second).
- Repeat the second and third steps at an elevation of 4 degrees and a 2000 microsecond pulse and an altitude of 500 km..
Run simulations of the Svalbard fixed with 2x the diameter
Create a new radar by giving the Svalbard fixed radar twice the diameter. To do this, you will need to know the following parameters about the Svalbard fixed ISR:
Build a low power Millstone Hill background ISR
The idea of this exercise is to build a low power version of the Millstone zenith antenna that can make a measurement every 5 minutes. To do this, use the Simulate a new ISR tool. Use the present zenith antenna which has the following characteristics:
Freq: 440E6 Hz
Diameter: 68 m
Pulse length: 480
Freq: 500E6 Hz
Present diameter: 42 m
Typical peak power: 1.0E6 W
Tau7 pulse length: 1920.0E-6 secondsTau7 pulse mode
0.05 duty cycle: 0.096
88 Jan 1, 81 degree elevation.
- Latitude 78 42 degrees, longitude 16 -71 degrees
Determine how many seconds low peak power you can reduce the integration period to and still have less than 20% error at all times at altitudes of:
1000 km
500 km
How much difference does this extra aperture make at 1000 km? At 500 km?
Now change the elevation at 5 degrees (its a virtual radar, after all!). What happens at 1000 km altitude? What parameter could you change to make things better at 1000 km?use to get 10% error at 500 km at 5 minutes integration across the entire day on Jan 1st..
