Abstract

Abstract:

As an important research direction of the radar system, W-band inverse synthetic aperture radar (ISAR), which is featured by high resolution, long detection range, miniaturization and lightweight, can be used as airborne, missile-borne and spaceborne applications. Microwave photonics technology is the main means to overcome the electronic bottleneck effect of the conventional radar due to high frequency band, large bandwidth and low loss transmission. A W-band frequency-modulated ISAR imaging system is proposed based on microwave photonics technology. In the transmitter, a W-band linearly frequency-modulated (LFM) signal with an instantaneous bandwidth of 8 GHz is generated using microwave photonic frequency multiplication. In the receiver, target echo signals are de-chirped based on microwave photonic de-chirp receiving. ISAR imaging simulation results show that the contours of the target in different postures are clear and discernible.

Key words: microwave photonics, W-band, imaging radar, inverse synthetic aperture
