ISR simulation tools

• Existing ISR simulator

• Simulate a new ISR

• ISR blackbox python module 

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: 192.0E-6 seconds

• Tau7 pulse mode duty cycle: 0.096

• Jan 1, 81 degree elevation.

Determine how many seconds you can reduce the integration period to and still have less than 5% error at all times at altitudes of:

• 1500 km

• 1000 km

• 500 km

With an integration time of ten seconds and all the parameters as above except peak power, how much do you need to set the peak power to to get a 5% error at 500 km?

Now change the elevation at 10 degrees (its a virtual Jicamarca radar, after all!). What is the integration time to have less than 5% error at all times at 1000 km altitude?
