radar detection

Data using X-band radar and small Styrofoam sphere target were mesured. The measurement system transmitted a linear frequency modulation waveform that had initial carrier frequency 9.35 GHz, stepped carrier frequency interval 0.2 MHz, solid state power amplifier (SSPA) power 50 W, bandwidth 5 MHz, polarization of HH, pulse-repetition interval 0.4 ms, pulse-processing interval 16 ms, scan-repetition interval 0.75 s, and scan-processing interval 15 s.
