Introduction to radar part vii 4 SAR system design

today , Let's look at the seventh chapter —— The last chapter of imaging radar （ Note that this is not the last chapter of this column ）, It is also the first 35 Chapter —— Design of synthetic aperture radar system . The contents of this chapter are as follows ：

35.1 SAR Radar range equation

• 35.1.1 Equivalent noise figure σ0

35.2 SAR Fuzzy situation

• 35.2.1 Avoid blurring the distance
• 35.2.2 Avoid Doppler blur
• 35.2.3 Grid lobe

35.3 Bandwidth and ground distance resolution

35.4 Beam width and azimuth resolution

35.5 Reduce sidelobe

35.6 SAR Design examples

35.7 summary

On board SAR The composition of the system is as follows ：

SAR The signal flow of is shown in the figure below
