Abstract

The detection and recognition of a target using a Millimetric Wave (MMW) radar is limited by its low power, inherent chirp demanding large bandwidth, system losses etc. Using coherent transmitter the detection range of a target can be improved. But it calls for one order of higher technology to develop a coherent transmitter. This paper presents a MMW active radar system which uses conventional IMPATT based transmitter with limited chirp but uses coherent techniques in the receiver. Coherency between the transmitter and the receiver is maintained by memorizing the transmitted waveform and using the same as reference for the receiver. System configuration along with the hardware feasibility is discussed in this paper.
