A radar system uses magnetron as high-power RF source. Its transmitter emits 300kW RF power at 10% duty factor. If the efficiency of radar transmitter during pulse is 60% and the power required during pulse off period is 1kW. The average power dissipation in radar is,
A broadside array operating at 100 cm wavelength consist of 4 half wave dipoles spaced 50 cm apart.Each element carries radio frequency current in the same phase and of magnitude 0.5 A. The radiated power will be _______ if the radiation resistance is 146 ohm.
For pulse radar with a maximum unambiguous range of 60 km, what is the maximum allowable pulse repetition frequency?
Consider a wireless communication link between a transmitter and a receiver located in free space, with finite and strictly positive capacity. If the effective areas of the transmitter and the receiver antennas, and the distance between them are all doubled, and everything else remains unchanged, the maximum capacity of the wireless link
Direction: Given question consists of two statements, one labeled as the 'Assertion (A)' and the other as 'Reason (R)'. You are to examine these two statements carefully and select the answers to these items using the codes given below.Assertion (A): The power handling capacity of a receiver antenna could be very low compared to the identical transmitting antenna.Reason (R): A transmitter antenna has to radiate a large power. The receiver antenna will have to deal only with a very small fraction of the radiated power from the transmitter.
Consider the following statements:The inter element spacing of1. More than \(λ\) in array antenna will produce grating lobes in unscanned condition.2. More than λ/2 but less than λ in array antenna will produce grating lobe under scanned condition.3. Less than λ/2 in array antenna will not produce any grating lobe.4. More than 1.5 λ in array antenna will not produce any grating lobe.Which of the above statements are correct?
A pulsed radar, operating at 3 GHz, having a pulse width of 2 μsec receives an echo from a target, 10 μsec after sending the signal. The approximate range of the target is
Match List I with List II and select the correct answer using the given below the list:List IList IIA. Two isotropes half wavelength apart fed in phaseB. Two isotropes quarter wavelength apart 90° phase shift2. C. Two isotropes quarter wavelength apart fed in phase3.
Directions: The item consists of two statements, one labelled as the ‘Assertion (A)’ and the other as ‘Reason (R)’.You are to examine these two statements carefully and select the answers to the item using the codes given below:Assertion (A): A Cassegrain antenna uses a main paraboloidal reflector and a relatively small hyperboloidal sub-reflector with a small horn-feed at the vertex of the main paraboloidal reflector.Reason (R): The optical technique developed by William Cassegrain was used in telescope design to obtain large magnification with a physically short telescope.This configuration is found to be effective in the design of microwave antenna also.
An axial magnetic field is applied to a cylindrical rod. The Faraday rotation of a plane-polarized beam after emergence from the rod is 5°. If both the field and length of the rod are doubled, then the angle of rotation is
