12. An eye safe LADAR system is used to detect an object at a distance of 1km. The center wavelength of the laser is 1580nm and it uses pulses at a rep rate of 1kHz and pulse duration 30ns. Determine: a. The maximum measurement range (minimum and maximum distance) limited by laser performance and not optics - Hint: think about how LADAR works, pulse duration and repetition frequency. b. The measurement range resolution c. The spot diameter at the target of distance 1km if the beam diameter at the exit of the laser is 5mm.
