An L-band low noise radar source
Abstract
Modern high-performance search radars are called upon to detect small targets in a heavy background clutter. For the MTI-system improvement factors to be of the order of 50 to 60 dB, the radar transmitter should be of a coherent type with Master Oscillator Power Amplifier (MOPA) configuration as against conventional magnetron oscillator. Consequently, there exists a need for a source with very high spectral purity. Presented are various aspects of design, development, and evaluation of such a source in the L-band. The source is based on solid-state low-noise stable local oscillator and stable master oscillator configurations for use in the receiver as a local oscillator, and as an exciter in the transmitter.
