Abstract In this paper, a new Synthetic Aperture Radar(SAR) signal of chaotic phase modulated intra-pulse and random coded inter-pulse is porposed depending on the characteristic of extreme initial value sensitivity and pseudo-randmoness and multidimensional hyperchaos. Four hyperchaotic phase modulated signals are compared detailedly and hyperchaotic logistic map phase modulated signal is proved to be best for SAR transmit signal. This signal is proved with an excellent exhibition on encryption and high Electronic Counter CounterMeasures(ECCM) performances.
