• Existing ISR simulator

• Simulate a new ISR

• ISR blackbox python module 

Part 1: Run simulations of the existing Poker Flat ISR

• Choose the Poker Flat ISR in Single Pulse 480 microsecond 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 10% error at all times at altitudes of:

  • 700 km

  • 500 km

• Describe what happens when the integration period gets short.

Part 2: Run simulations of

a modified Poker Flat ISR

Modify the Poker Flat radar by making it larger or smallerCreate 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 Poker Flat 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?
