Abstract

In the field of laser radars, there has been limited work on long-wave pulse-burst waveforms with pulse widths in the nanosecond regime. This waveform has several advantages over other waveforms, e.g., excellent range resolution with small doppler ambiguities. Phillips Lab has developed a flexible ladar to provide the means of obtaining images and signatures of hard body objects under controlled laboratory conditions. The transmitter laser is also capable of frequency agility operation to support remote sensing experiments. A coherent, pulse-tone, pulse-burst CO₂ TEA laser radar operating at 10.6 micrometers is described. The pulse train is obtained by actively mode locking with an intracavity germanium standing wave acousto- optic modulator. Approximately two hundred pulses per burst are transmitted at a repetition rate of 83 MHz. Injection seeding and cavity matching produces a pulse tone waveform. An overall transceiver system bandwidth of 1 GHz is employed. The device was developed as a flexible platform to support scaled risk reduction and phenomenology experiments.
