Abstract
This paper consists of a technique to design a Chirp radar system and proposes a solution to optimize the design of the linear time delay network required in such systems. A Chirp radar system has a wide bandwidth for high range resolution, and long pulse duration for high velocity resolution and high transmitted energy. The technique of a pulse compression system offers a means of increasing the average power available to illuminate radar targets without any loss of the resolution at the receiver needed for the tactical requirements of the system. This is accomplished by transmitting a wide pulse in which the carrier is frequency modulated and then, by proper signal processing methods, causing a time compression of the received signal to a much narrower pulse of high effective peak power. The pulse compression occurs when a waveform with a linear frequency modulation and a nonlinear phase spectrum is passed through a network which is "phase matched" to the waveform. The spectra and time functions of a particular class of pulse compression signals are analyzed and the details of the compression network design are derived.
