Some issues in the development of metric surveillance radar

Because of its low detection accuracy, inaccurate height-finding, and discontinuous airspace coverage, the meter-wave radar has been replaced by common microwave radar progressively in the development course of radar. However, for the threat from stealth aircraft, the meter-wave radar has unique frequency-band advantage. Combined with the research work of many years, the author makes an introduction to the methods for solving the major drawbacks existing in the traditional meter-wave radar by use of the meter-wave synthetic impulse and aperture radar (SIAR) and the super-resolution processing. The research and experiment results indicate that these drawbacks can be overcome effectively. The meter-wave radar will have a good development perspective.
