The Performance Analysis of Up and Down LFM Based on Multi-Pulsed SimultaneousPolarimetric Measurement Technique

Polarimetric measurement and dada calibration is the base of obtain of radar polarimetric information, and the style of polarimetric measurement and the selected waveform have an important influence on it. In this paper, a briefly introduction about the commonly interleaved-pulsed polarimetric measurement technique and the simultaneous pulsed polarimetric measurement technique is presented. The ambiguity function and the waveform isolation function of up and down LFM signal have been studied based on multi-pulsed simultaneous polarimetric measurement technique in this paper, the theory derivation and the simulation experiment show the ambiguity function of the waveform is determined by the time-band width product and the waveform isolation is the function of the time-band width product, the waveform have a well performance in the Doppler toleration.
