Other AbstractPulse Dopp ler radar p rovides impo rtant application in GMTI. Space-based GMTI radar system is widely given at ten t ion becau se it sdetection performance and adap tab ility excel that of airbo rne system.In this paper, based on the characterist ics and recen tresearch of space-based dist ribu ted sparse apertu re GMTI radar system ,the characterist ics of space-based GMTI radar system are deep ly invest igated. The an tenna pattern of sparse apertu re space2based GMTI radar and the fu ll2DOA op timum STAPSINR loss characterist ics are provided and analyzed.By analyzing sparse apertu re space2based GMTI radar space2t ine 2D f iltering algo rithm ,the RD2STAP( reduced dimen sion STAP) algo rithm s including ADPCA ,postDopp ler and PR I2staggered STA P algo rithm are in t roduced. Based on the space-based dist ribu ted un ifo rm linear array GMTI radar system parameters, the perfo rmance compare of the STA P algo rithm s are ob tained.Resu lt s show that the RD2STA P algo rithm s ob tain the sat isf ied SINR lo ss perfo rmance with lim ited training samples.In the end, the p ro spect s of the space2based GMTI radar system and signal processing research are provided.
