The basic equation for pulse-radar maximum-range calculation is presented in a form convenient for numerical computation. Charts, graphs, tables, and auxiliary equations are presented for evaluation of the various factors in the range equation. Included are graphs for the required signal-to- noise ...
The author introduces an equation defining the range to an object and to its elements for radar using ultra-wideband sounding signals and ultrashort pulses. The equation is based on determination of autocorrelation characteristics of the signal received. The paper contains an example of analysis of ...

Radar range equation Detection of objects using radar involves sophisticated signal processing. For a single pulse the following signal to noise ratio is: Observe that the received power drops with the fourth power of the range, so radar systems must cope with very large dynamic ranges in the re...
In a radar, pulse droop equates to range reduction over the length of the pulse—the combination of pulse amplitude and pulse width determines the range of the radar as an integrated power level. The radar equation, as it is known, defines the trade-offs and th...
This example shows how to build, simulate, and deploy a pulse-Doppler radar system in Simulink® using an SoC Blockset™ implementation targeted on the AMD® Zynq® UltraScale+™ RFSoC evaluation kit. Using this example, you can detect and estimate the range and velocity of moving ...
The short pulse equation (SPE) is considered as an initial-boundary value problem. It is found that the solutions of the SPE must satisfy an integral relation otherwise the temporal derivative exhibits discontinuities. This integral relation is not necessary for a solution to exist. An infinite nu...
