Calculate range resolution of a synthetic aperture radar, if the pulse width is 3μsec. (Assume c = 3 x 108 m/s) 450m 900m 300m 600m

What is the total distance travelled by a pulse of frequency 3μsec from the antenna to the target and back? (Assume c = 3 x 108 m/s) 600m 450m 300m 900m

Consider the coherent ground-based pulsed radar that operates at a carrier frequency of 10 GHz, a PRF of 5 kHz, a duty cycle of 5%, and transmits LFM pulses with 100 MHz bandwidth. Plot the range domain of the signal received from a target at a distance of 10 km from the radar before and after matched filtering (pulse or range compression).

A radar is able to detect the reflected waves from an enemy aeroplane after a time interval of 0.02 millisecond. If the velocity of the waves is  3 × 108ms−1 , calculate the distance of aeroplane from the radar (in  km  ).

Best possible resolution that can be achieved by SAR is when length of antenna = X * Azimuth Resolution. What is the value of X? 1/2 1/4 2.0 4.0

ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements.Calculate the wavelength of a radio wave whose frequency is 900.0 kHz. (v = 3.00 · 108 m/s.)_____ m3.333 x 10 113.333 x 10 22.700 x 10 143.333 x 10 5
