Description
Summary:Computer technique was developed to simulate basic parameters of spaceborne synthetic aperture radars operating in the pulsed mode. Relationships are obtained and presented that make it possible to calculate dimensions of the antenna aperture, repetition period of the transmitter pulses and their duration, as well as duration of the pulse strobes opening the receiving device input, size of the antenna aperture, radiometric sensitivity and resolution, transmitter pulse power, bandwidth of the signal modulating the carrier frequency, aperture synthesis time and information flow rate. The technique is implemented on a personal computer in the C++ environment. The program menu with windows for input of initial data and output of simulation results is presented displayed in the form of 9 types of parametric dependences of the SAR characteristics on the observation point viewing angle. Technique introduction makes it possible to quickly, conveniently and with satisfactory accuracy perform systematic assessment of the SAR main characteristics choosing the most preferable options in the equipment basic parameter combinations.
