Design Optimization of Signal Timing for Multimode Integrated Microwave Remote Sensors

Altimeters, spectrometers, scatterometers, and synthetic aperture radars (SARs) are widely used for detecting marine dynamic elements. The development of multimode integrated microwave remote sensors has become a trending research topic in the field of microwave remote sensing; a single load on a satellite presents relatively few functions, and multiple loads on a satellite create large volume and mass and high operational risks. The system parameters of a multimode integrated microwave remote sensor are designed, and then the minimum energy of the transmitted signal is taken as the optimization objective function. The constraints are defined in many aspects, and a time sequence optimization model of the signal for the multimode integrated microwave remote sensor is established. The genetic algorithm is used to solve the established optimization model. The simulation results show that the proposed optimization method can design a signal timing that meets a variety of constraints and requires minimal energy.
