Unformatted text preview: left antenna a time ago. (This time delay of the left signal can be easily accomplished with the proper electronic circuit.) Find the time delay if the object t be viewed is at an angle θ to the vertical. 2. Stealth aircraft are designed to not reflect radar, whose wavelength is typically 2 cm , by using an antireflecting coating. Ignoring any change in wavelength in the coating, estimate its thickness. 3. A radar speed detector works by reflecting microwaves off a car and measuring the change in the frequency. If waves of frequency 4 × 1010 Hz are measured to be 2 × 103 Hz lower in frequency af...
