What is difference between pulse radar and CW radar?
CW or continuous-wave radar cannot determine range due to the lack of a listening period where the radar signal is silent. Pulse radar has a silent listening period (hence the name pulse radar). Therefore it can determine the range of the object causing the return by counting the elapsed time between transmission and receipt of the echo. The above is not quite correct, Continuous Wave Radar and Pulsed Radar differ by there relationship between the Pulse Width (tau) and the scene size (Swath). CW Radar's determine range by Frequency Modulation (FM) ranging this means that they ramp the RF frequency within the pulse during the transmission and are known as FMCW Radar. Pulsed Radar on the other hand use the pulse timing but can also use the FM Ranging trick to enhanced there signal to noise and reduce there probability of interference or detection/interception. CW radar can deduce range by delaying the transmit signal and mixing it with the receive such that it becomes a homodyne receiver and in such cases it is usual to ramp the RF and perhaps use two aerials rather then just one with a duplexer switch like in a Pulse radar system. Edit- hmm i feel the above answer is bit too complex... i don't think typical person would go as far as concerning FM or Pulse Delay Ranging here's my Answer DIFFERENCES BETWEEN PULSE AND CW RADAR Basis -Transmission Pulse RADAR puts delay between transmitting and receiving periods so the time between transmitted pulse and received pulse is different While CW RADAR, Transmit continuously -Antennas Pulse RADAR may use same antenna for Receiving and Transmitting , when transmitting the receiver is "blanked" and while Receiving the receiver is Activated and transmitter is blanked .. this is done by a device called "Duplexer" CW RADAR typically used 2 Antennas, one for transmit another one to Receive since there are no delay to receive as what usually seen in pulse RADAR -Ranging technique Pulse RADAR may use "Pulse Delay Ranging" to provide Range measurements , Frequency Modulation Ranging may also possible , especially for pulse RADAR that transmit many pulses and have very shot time to "listen" example is FMICW (Frequency Modulated Interrupted Continuous Wave RADAR) While CW RADAR provides Range by means of Doppler based Ranging (FM Ranging)
What is a radar mast?
A radar mast is a high platform to mount a radar antenna such as the radar has an unobstructed view.
What is theDifference between acquisition radar and guidance radar?
In a Military contact Acquisition Radar normally refers to the Search Mode Radar used to scan and track targets before being "target tracked". In this context the "target tracking radar" is used for track and perhaps illuminating a target. If this radar is being used to guide an weapon to the target it is referred to as a guidance radar. However Guidance radar can also exist in the missile seekers.
Did Bismark have radar?
Bismarck certainly had radar but it may only have been gunnery radar similar to that on the Graf Spee in 1939.
How do you use a Radar?
That depends on the particular radar system. A simple speed radar used by law enforcement can simply be held and pointed at a target to determine the speed of the target. A more complex system like an air traffic control radar system would have display consoles for the radar operator to view the data.
What type of device is a duplexer?
A duplexer may refer to a device used in radar and radio communications systems that allows for bi-directional communication, meaning that it allows the user to both send and receive messages. It may also refer to the component of a printer that allows it to simultaneously print both sides of a sheet of paper.
What is a duplexer?
A duplexer is a device that allows bi-directional (duplex) communication over a single channel. In radar systems, a device that isolates the receiver from the transmitter while permitting them to share a common antenna. Note 1: A duplexer must be designed for operation in the frequency band used by the receiver and transmitter, and must be capable of handling the output power of the transmitter. Note 2: A duplexer must provide adequate rejection of transmitter noise occurring at the receive frequency, and must be designed to operate at, or less than, the frequency separation between the transmitter and receiver. Note 3: A duplexer must provide sufficient isolation to prevent receiver desensitization.Braimah prosper
A duplexer is used?
There are several kinds of equipment called a "duplexer", including: * In telecommunications, a duplexer is a device that combines two or more signals into a common channel or medium to increase its transmission efficiency. Simply put the duplexer allows the antenna to be shared between transmit and receiv. * In printing, a duplexer is used to print on both sides of the paper. * ...
Block diagram mti radar and its working?
In an MTI (Moving Target Indication) radar system, the block diagram consists of a transmit/receive antenna, a duplexer to switch between sending and receiving modes, a radar signal processor to detect moving targets, and a display unit for visualization. The radar sends out a series of pulses and examines the return signal to detect targets with a non-zero Doppler shift, indicating movement. The radar signal processor filters out stationary clutter and focuses on moving targets, displaying their position and velocity on the radar screen.
What are the price ranges for an HP Duplexer?
HP Duplexer printers are priced according to the specifications of the printers. Some of the basic printers are priced under $50. The more deluxe models sell for as much as $500.
