ABSTRACT:
4. A strobe generator for a radar set which includes a rotatable directio antenna, a plan position indicator and has an interpulse period defined by the time between transmitted pulses, comprising; means to sweep said rotatable directional antenna past a source of enemy jamming signals, means to produce pulses of one polarity in response to increasing jamming signal strength on said antenna and pulses of the opposite polarity in response to decreasing jamming signal strength thereon, a first monostable multivibrator, said pulses being applied to said first monostable multivibrator, said first multivibrator being triggered only by said pulses of said one polarity, the output of said first multivibrator being applied to a second monostable multivibrator with a pulse length longer than the interpulse period of said radar set and means responsive to the resetting of said second multivibrator for initiating a strobe pulse for application to said plan position indicator of said radar set.
