Python script for calculation of Radial velocity of target using CWR

Script:

Output:

Continuous Wave Radar

 

Assume 

The E-field transmitted can be written as below

The returned E-field at some time later is

Time it took to travel to and from the object(target) is

Substituting

The received frequency can be calculated by taking time derivative of the quantity in red above and dividing by 2pi

 

Here,  

 

  

 

The blue coloured quantity above is nothing but he Doppler shift frequency.

Here the sign essentially indicates the target moving direction

If the doppler shift is negative then the target is moving away from the radar and vice versa

And thus the velocity can be written as

Introduction to Verilog

Verilog is a type of Hardware Description Language (HDL). Verilog is one of the two languages used by education and business to design FPGAs and ASICs.
