Question

In Module 7, you explored the capabilities and applications of ground-based and airborne radar and SAR systems used to support both data collection and sense and avoid functions. Given what you have learned about these sensor types, identify the strengths, weaknesses, and several example applications for both primary data collection and separation assurance tasks. How do you think radar systems compare to the sensor types explored to this point for primary collection of targets on the ground and in support of obstacle or aircraft sense and avoid requirements? Can you identify any needs for additional development to make radar or SAR systems more viable for widespread incorporation into UAS, particularly small platforms? Be sure to consider issues related to range, power, size, weight, cost, etc

Explanation / Answer

ground based ad airborne radar are used for the measurement and imaging og the site and the field. in ground based radar waves has been transmitted and signal recieved by the antina and data stored in the memory of the system. same process has repeated in the airborne radar but there is the main difference between airborne radar and groundbased radar is that airborne radar is mounted on the moving object like aircraft .in this radar waves transmitted perpendicularly to the surface and recieved by the reciever and generate images and data. SAR is the type of the airborne radar basically but its a advanced system than airborne radar. in it images generated in 2d and 3d . in SAR image quality is so high in comaprision of those system. SAR is also mounted on the moving object and transmitted electromagnetic waved to the site or the field and reflected waves for the object are recieved and stored by the antena for the further process. . for 3d image its worked on two steps. firstly it generate 2d image and then with help of DEM it measure the phase differences betwwen the complex images. then we will get height information. and azimuth range coordinations are provided by the 2d images . with wholee process generate 3d image.

but sinusoids closers cannot be seperated by the SAR create obstacle in the data compiling. applications for these radar systems are survelliance, field measurement, prospecting, tracking and in other machines and technology its played very important role like in anti-defence ballistic missile system. .

there is many difficulties when data measured so we have to find the solution of them becaouse with tghose difficulties there is many chances to happen mistake.
