You may be able to have smaller antennae for the same resolution.
If you use the same size of antenna, then spatial resolution will increase, provided the equipment has been so designed.

If a frequency of a wave increases what will happen?
Increase decrease. The frequency MUST decrease.
Sonar machines rely on which property of sound waves?
frequency?diffusion?refraction?reflection? QDA SUCKS!
An increase to a sounds pitch corresponds to increase to what other property?
Frequency! :)
An increase in a sound's pitch corresponds to an increase in what other property?
frequency
What happens to period when frequency increase?
Time period = 1 / frequency. Frequency = 1 / time period. When frequency increases, the period decrises.
What will happen to the wavelength if the frequency is decreased?
the wave length will increase
If a frequency of a wave increases what will happen?
Increase decrease. The frequency MUST decrease.
What would happen to the wave length if you could increase the frequency of a periodic wave?
If you increase the frequency of a periodic wave, the wave length decreases proportionally.
What would happen if the length of wire increase what happens to frequency?
frequecy will not change
Why do narwhals communicate?
because they have high frequency sonar pings
What is the maximum frequency of a sonar before it effects wildlife?
The freqeuncy (or pitch) of the sonar is not generally the factor which is likely to effect wildlife, but the amplitude (how loud it is).
What are the three parameters of sound that can be measured by the SONAR?
Return timeAmplitudeDoppler frequency shift
What does LFAS stand for?
Low Frequency Active Sonar
When wavelength decreases does the frequency increase or decrease?
The wavelength is inverse to the frequency, meaning the frequency in this case will increase.
Are pink dolphins and submarines the same because they use the same sonar?
Though they both use SONAR (SOund Navigation And Ranging) to navigate, submarines and marine mammals that use sonar are both very different in how they use it.Marine mammal sonar uses a much higher frequency than submarine active sonar systems transmit at. Also, submarines rarely use active sonar due to the fact it immediately gives away your location and range to an enemy. Marine mammals use their active sonar constantly to navigate through the water, communicate, and to find food, while passive sonar is the primary means of submarine navigation.Dolphin sonar sounds like a fast clicking sound, with occasional high frequency "squeals", similar to a dog toy, though at a much higher frequency range. The frequency is high enough that it must be demodulated by special equipment to a lower frequency to really hear it. Usually when submarines go to periscope depth, dolphins set off the torpedo warning alarms since their frequency is at a similar range. As a former Submarine Sonarman, I can also say that it also drives you nuts, especially when there's a whole group of them around the boat.
Why is nthe speed of a sonar signal inwater with the frequency of 1000 hz and a wavelength of 1.5m?
The familiar formula for finding the speed of wave right from its frequency and wavelength is c = nu lambda. nu is the frequency and lambda is the wavelength. So in this case speed of sonar signal = 1000 x 1.5 = 1500 m/s.
