ISR simulation tools

Run simulations of the existing Jicamarca ISR

  • Choose the Jicamarca ISR in long pulse mode

  • Run for 24 hours during Jan. 1st at a 90 degree elevation using 60 seconds of integration

  • 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

  • Describe what happens when the integration period gets short.

Run simulations of the Jicamarca moved to the polar region

Move the Jicamarca radar to latitude 85, longitude 0 by switching to the virtual radar tool. You will need the following details about the Jicamarca ISR:

  • Freq: 49.92E6 Hz

  • Effective diameter: 329 m

  • Typical peak power: 2.0E6 W

  • Long pulse length: 1600.0E-6 seconds

  • Long pulse mode duty cycle: 0.038

  • Jan 1, 90 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?
