ISR simulation tools

Run simulations of the existing Arecibo ISR

  • Choose the Arecibo ISR in topside mode

  • Run for 24 hours during Jan. 1st at a 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:

    • 2000 km

    • 1500 km

    • 1000 km

Run simulations of the Arecibo moved to the polar region

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

  • Freq: 430.0E6 Hz

  • Diameter: 305 m

  • Typical peak power: 1.5E6 W

  • Topside mode single pulse length: 500.0E-6 seconds

  • Topside mode duty cycle: 0.025

Repeat the same simulations for altitudes of 2000, 1500, and 1000 by changing only integration time.

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