Blind speed in radar
Web2. If two MTI radar system are operating at the same PRF but with the different operating frequencies and the second blind speed of one is equal to fourth speed of the other radar. Find the ratio of their operating frequencies. [2 Marks) [1 Mark] 3. Pulse compression results in a). Increase in both Signal Power and Noise Power b). WebIn Fig. 5.5, the first blind speed v1 is plotted as a function of the maximum unambiguous range (Runamb = cT / 2), with radar frequency as the parameter. If the first blind speed were 600 ...

Blind speed in radar
Did you know?
WebA radar unit works with the tx-frequency of 2.8 GHz and a puls repetition time of 1.5 ms. Under these conditions the first blind speed has got the value: v blind = 8λ = c 0 = 3·10 … Webradar using phase cancellation MTI would not produce a video pulse for a target moving at the radar blind speed. In looking at the formula Vb= PRT it can be seen that the blind speed Vb is a function of transmitter Frequency and pulse repetition time. It can also be seen that if the PRT is changed the blind speed will be changed.
WebThe blind range for a radar system is the distance occupied by the transmit pulse and the setup time for the receiver. ... For example, if a radar rotates at a fixed speed of 4 RPM, then the scan time is 15 seconds (60/4). Scan time performance interacts with high-speed objects. Excessive scan time allows high-speed objects to travel a large ... WebRadar is an acronym for RAdio Detecting And Ranging. The name itself suggests that the radars are used to detect the presence of object and determine its range, i.e., Fig. 1: A Representational Image of RADAR or Radio Detecting and Ranging used to Detect Presence and Range of an Object. distance and bearing, using radio frequency waves.
WebThe pulse width ( ) (or pulse duration) of the transmitted signal is the time, typically in microseconds, each pulse lasts. If the pulse is not a perfect square wave, the time is typically measured between the 50% power levels of the rising and falling edges of the pulse. The pulse width must be long enough to ensure that the radar emits ... Webblind speeds.
