ISR simulation tools
Run simulations of the existing Svalbard ISR
Choose the Svalbard Fixed (up B) ISR in tau7 mode
Run for 24 hours during Jan. 1st at a 81 degree elevation using 240 seconds of integration
Determine how many seconds you can reduce the integration period to and still have less than 20% error at all times at altitudes of:
1000 km
500 km
Describe what happens when the integration period gets short.
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:
Freq: 500E6 Hz
Present diameter: 42 m
Typical peak power: 1.0E6 W
Tau7 pulse length: 1920.0E-6 seconds
Tau7 pulse mode duty cycle: 0.096
Jan 1, 81 degree elevation.
- Latitude 78 degrees, longitude 16 degrees
Determine how many seconds 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?
